The simulation results show that DMC is the optimal control law.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121421814","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}

We introduced the magneto-rheological fluid (MRF) technology, and the mechanical structure of a new servo-controlled damping pneumatic rotary actuator is designed. The positioning servo system of the new pneumatic rotary actuator is constructed and the mathematical model is established in this paper. The MRF damper characteristics of torque and dynamic response are investigated through experiments. The experiments show that the positioning servo system using control algorithms of braking angle compensation provides more robust against the pressure fluctuation and it can provide the precision positioning under different loads with arbitrary speed and point. The research provides theoretical and experimental basis for the MRF technology application in the pneumatic rotary positioning servo control.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129017037","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}

Aiming at this problem, the two typical pipelines (straight pipe and curved pipe) were analyzed using the Finite Element Method (FEM) in ADINA software. Compared with the experiment, the results from ADINA simulation are close to the experiment data. Based on the simulation results, we concluded that adjusting the clamped-end length or consolidating the pipe are effective ways to change the natural frequencies of fluid-filled pipe and prevent the drastic vibration of the pipeline system in aircraft when the natural frequencies of the fluid-filled pipe fall into the frequency range of vibration source.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128665711","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}

AC motors have relatively small volume, but cannot have the ball controlled as accurately as DC motors, which are more ponderous, through a traditional control method such as PID. In order to acquire both perfect control accuracy and small volume, we plan to take the strategy of controlling the AC motor with vector control, which can make AC motor perform as well as DC motor on speed regulation, through series of transformations, such as two-dimensional coordinate transformation and rotation transformation. This paper presents a mathematical model of the ball target driven by vector-control AC motor. Then the model is built and simulated in MATLAB/Simulink. Simulation results indicate that vector control is effective in controlling the AC motor to drive the ball target.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116927460","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}

So, a co-simulation approach should be presented. In this paper, software RecurDyn was used to run the dynamic model of crawler driving system. The mechanical parameters of dynamic simulation were used to establish a data table, which was input to the hydraulic system model that established by the software SimulationX. Results of hydraulic system were obtained after simulation in both forward driving and backward driving working conditions. Comparing the simulation results with theoretical calculation results, it proved that this approach was more accurate and faster operational speed.
