There should be an effective control system to run the vehicle for maximum efficiency by reducing the losses such as parasitic losses, frictional loses, power train loses, rolling resistances, loses occurs while applying braking. For achieving this, ECU needs complete knowledge about not only the engine performances, but also essentially vehicle behaviour, environmental parameters such as road slope, rolling résistance, and wind resistance. Analogy method is a well known method of estimating the various system parameters and its performances. In this paper, a discussion about how to analyze the vehicle dynamic system behaviour thermodynamically thereby to make ECU works efficiently. In some thermodynamic systems, certain properties can be observed as similar to vehicle's behaviour in such a way that energy transfers taken among the systems are usually governed by the same algorithm. Some ideal thermodynamic properties such as work, energy, internal energy, enthalpy, entropy are very useful for investigating the overall system performances of the vehicle. In this paper, a selective thermodynamic system is taken to study the vehicle's dynamics of the automobiles using analogy method. The data required to the ECU such as speed, torque required, acceleration and kinetic energy gained by the vehicle can be calculated through thermodynamic relations such as enthalpy, entropy and internal energy. The various thermodynamic processes and cycles can be made analogue with some selective vehicle dynamic processes. The data obtained from analogy models can be fed into ECU and ECU can manipulate the data to increase the performance of the vehicle.","PeriodicalId":161131,"journal":{"name":"2015 International Conference on Robotics, Automation, Control and Embedded Systems (RACE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129614467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a method is presented for controlling the multivariable processes in a laboratory reactor system mimicking the real time deep-sea conditions. Relative Gain Array method based decoupling controller for deep-sea parameters such as pressure and temperature was designed in order to minimize the interaction effects between the parameters. Pressure in the ocean increases by about 1 atmosphere for every 10 meters of depth, the amount of pressure experienced by many deep-sea organisms is extreme and temperature varies from -2° C to 300° C based on the location, depth, hydrothermal vent etc. For this purpose, a real time data has been generated from the Deep-sea Microbial Culture facility system and system transfer functions are identified. Various manipulated variables interacting and influencing the MIMO system are analyzed and identified. Using MATLAB system identification tools, the suitable numbers of manipulated variables involved in the transfer function model are identified and the best fit was evaluated using various methods. The operation of the MIMO based decoupled PI controller for deep-sea laboratory system was studied for reference tracking and cases of disturbance rejection. The performance indices of the controller are calculated, compared, analyzed and presented. Simulation results endorse the efficiency of the proposed control system.","PeriodicalId":161131,"journal":{"name":"2015 International Conference on Robotics, Automation, Control and Embedded Systems (RACE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130681038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two practices followed in robotic deburring, viz., the work piece is held by the robot's gripper while the deburring tool is external to the robot and the second mode, the deburring tool is held by the gripper with the work piece is held in a fixture external to the robot. The second mode is the focus of the present paper. In deburring operations, the forces exerted are very small in the case of small and medium sized components machined earlier by fine cuts with a small depth of cut, and therefore the deburring forces are neglected in the present analysis. A SCARA robot fabricated in-house has been utilized for the video graphic analysis. The recorded video is analyzed using any of the many video players to trace the path taken by the robot's quill. This data is utilized as inputs for the mathematical analysis and animation studies. Kinematic equations of a SCARA robot are derived using Denavit-Hartenberg notation. Mathematical equations for kinematic parameters and torques are derived. Kinematic parameters include joint angles, joint velocities, and joint accelerations. Mathematical analysis has been carried out using MATLAB software. The same SCARA robot is modelled and simulated for the path taken during deburring using CAD software and the analysis is carried for kinematic parameters .Comparisons are made for results obtained by the above mentioned three methods and graphs are drawn for joint angles, joint velocities, joint accelerations. Important conclusions are drawn for the robotic deburring operations using SCARA robots.","PeriodicalId":161131,"journal":{"name":"2015 International Conference on Robotics, Automation, Control and Embedded Systems (RACE)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132781088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Productions of complicated parts were difficult and batch production also impossible. The dimensions between the parts were varied so to produce batch production, testing was required. So, the cost of production was increased. Manual operated machines are now a day retrofitted by using electrical, electronics and computer software and programming technologies. The axes movements and spindle speed are driven by electrical motors. So, the no of axes can be increased which is depending upon the job's complication. Limit sensors are installed and interfaced. When a particular axis movements are exceeds its limit, the sensors will send the signals and the direction pulses are send which is used to stop the corresponding axes movement actuators. The direction and control pulses are sent from the computer to driver electronics. Actuator terminals are connected with driver electronics. Using CAD/CAM software, 3D modelling and other CNC programming parts are designed and then G-codes and M-codes are generated. The codes are executed line by line. The axes are moved with respect to the codes. Finally the one can obtain the designed parts. So, batch production will become very easy. In that particular production, dimensions between the parts are exactly similar to each other. No need to test every parts individually. Production time is less so no of products are increased.","PeriodicalId":161131,"journal":{"name":"2015 International Conference on Robotics, Automation, Control and Embedded Systems (RACE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133763373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The response considered for the analysis was surface roughness. The results indicated that A356-5TiB2 composite produces higher tool wear, surface roughness and minimizes the cutting forces. Moreover, there was improvement in the quality of the machined surface in the A356-5TiB2 composite compared to A356 alloy. The chips formed during turning were characterized by Scanning Electron Microscope and analyzed from the machinability point of view. Optimum machining parameters for minimizing the surface roughness were determined.

This work reviews on the research aspects in the condition monitoring of Abrasive Water Jet Machining (AWJM) system. Condition monitoring of the AWJM system helps to achieve an effective utilization of the machine in order to increase productivity. AWJM is one of the non-traditional machining processes used to machine difficult-to-machine materials. It works on the principles of erosion of material by the action of high velocity water jet mixed with abrasive particles and air. The input parameters involved in the AWJM system are water jet pressure, abrasive flow rate, orifice diameter, nozzle diameter, particle size of the abrasive, abrasive type, etc. Researchers have carried out condition monitoring of AWJM system using different sensors such as Acoustic Emission (AE), accelerometer, cutting force dynamometer, sound, thermograms, etc. Among the sensors, it is observed that the AE sensor is widely used in AWJM system for monitoring. From the review, it is observed that the acquired sensor signals are correlated with output parameters such as nozzle wear, depth of cut, surface texture, jet energy, jet penetration, stand-off distance, etc. The future work recommends the condition monitoring of AWJM system using multi-sensory approach with suitable sensors.","PeriodicalId":161131,"journal":{"name":"2015 International Conference on Robotics, Automation, Control and Embedded Systems (RACE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131108850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
