To this end, a state feedback controller is designed for the nominal system and then a disturbance observer based feedforward control is added in order to reject uncertainties. In doing so, the DOB and state feedback controller are united in a way that the combined control satisfies the input constraints and closed loop stability is guaranteed. Simulation results are given to show that the proposed control scheme successfully stabilizes the uncertain systems.","PeriodicalId":6641,"journal":{"name":"2015 15th International Conference on Control, Automation and Systems (ICCAS)","volume":"124 1","pages":"290-294"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88082449","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}

Due to the use of angular encoders as the sensing device for joint actuation, robot movement is limited within discrete positions in its reachable workspace. The absolute accuracy of the end effector depends on the resolution of the actuated joints. It is associated with the accuracy of the work. It is necessary to analyze this situation. In this paper, we analyzed the effect on the robot's operation and its effect on the discrete resolution in its joints and links of the robot, and studied the characteristics of the approach direction and distance from the origin for joint movement with a discrete resolution.","PeriodicalId":6641,"journal":{"name":"2015 15th International Conference on Control, Automation and Systems (ICCAS)","volume":"9 1","pages":"2087-2090"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84313739","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 basic configuration of the system uses the gyroscopic effect which generates the yawing force as a control input. The friction combined with yawing force enables a robot system to maintain the lateral balance. Although this horizontal configuration gives a better pitching stability to the body system, enough friction and momentum must be guaranteed to perform the successful control task. To make a power-efficient system, in this paper, rolling force-based control configuration, namely the vertical configuration is proposed. Although this configuration has a major disadvantage in its pitching instability problem, efficient power consumption can be achieved. The pitch instability suppression is suggested to improve the balancing control algorithm performance. Experimental studies confirm that the power-consumption has been dramatically reduced and the correctness of instability suppression algorithm is properly verified.","PeriodicalId":6641,"journal":{"name":"2015 15th International Conference on Control, Automation and Systems (ICCAS)","volume":"14 1","pages":"570-573"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87118791","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 which, a sigmoid function is substituted for the signum function with a variable boundary layer. A SHSM observer is proposed to provide the estimation of back electro motive forces (EMFs) that are treated as unknown inputs in the PMSM model. An accurate speed estimate of PMSM can be algebraically computed with the estimated back EMFs. The chattering phenomenon, that is commonly found in the sliding mode observers is well-reduced by replacing signum function with the sigmoid function, in comparison to the HOSM observer. Simulation results show the effectiveness of the proposed SHSM speed estimation method in comparison to the earlier HOSM observer in terms of good accuracy and chattering phenomenon.","PeriodicalId":6641,"journal":{"name":"2015 15th International Conference on Control, Automation and Systems (ICCAS)","volume":"1 1","pages":"1612-1617"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88276883","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}

Consideration of these issues is impossible without corresponding data support, which is necessary for organizational tasks and for the entire cycle of medical data processing, starting from data collection, through a comprehensive analysis and issue of recommendation. Using modern software, communication and intelligent technologies promises not only improving of geriatric care quality but reducing the cost and social-economic benefits.

These problems are in the joint and with links. Another problem is their complex dynamics that make control of this robot have some challenges. Non-linearity, interaction between loops and flexibility in the joint cause this problem. The present paper has focused to improve the tracking performance of these robots. Therefore, at the first step, we need to use physical relations of system and determine a model for the FJR. In this paper, the Fuzzy Logic Self- Tuning PID (FLST-PID) controller will be introduced to keep the rotating angle of the link of FJR at desired position. In the classic PID forms, the parameter values of the controller i.e. Kp, Ki, Kd are calculated in many various methods like Ziegler-Nichols and are constant. In FLST-PID, the parameter values computed by intelligent methods like fuzzy logic and they vary during the controlling process. For demonstrating the ability of the proposed controller, some classic controller like PID, LQR and State Feedback will be designed for FJR and the response of the system with these controllers will be compared. Moreover, by considering some uncertainty on systems parameters, the comparison will be performed once again. Simulation results confirm the claims and show that the proposed controller has the best response for the system especially in uncertainty conditions.","PeriodicalId":6641,"journal":{"name":"2015 15th International Conference on Control, Automation and Systems (ICCAS)","volume":"1 1","pages":"186-191"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86166635","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}

A mathematical model of a system describing the interaction between an unactuated barge ship and mooring system is presented. A PID control scheme is implemented to achieve PM for the vessel by changing the tension of the mooring ropes. Additionally, a scale model ship is built to test the proposed strategy.
