This paper discusses the importance of pump/motor design on the driveline efficiency and operating costs of mobile machines. Reliable and precise loss models of hydrostatic units are essential for this investigation, driving requirements for special attention to efficiency measurement and modeling. The energy saving potential, and the reduced needed cooling power combined with additional losses, results in lowering direct operating costs in the range of thousands of $ per year.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"7 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":"115722132","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}

By means of improving from the traditional throttle loop to load sensing circuit which is consisted of the electro hydraulic proportional valve and load sensing pump, the hydraulic system has been improved to realize a flexible conversion of variety working conditions.

This cancels the gap and simplifies the machine. However, in motion simulator, changing loads endues it with uncertainty. The LQG (Linear Quadratic Gaussian) control law which is widely used in aeronautics is based on a state representation to control. This sort of control law integrates a Kalman filter that estimates the state space vector of the system, and an optimized state feedback depending on one quadratic criterion. The LTR (Loop Transfer Recovery) tuning is also used and provides an excellent robustness/performance compromise. The LQG-LTR control law is proposed for a single axis motion simulator, which is a DDR rotary position servo system with uncertain inertia load, in this paper. Mathematical model is built, based on which some analyses, which focus on the uncertain load, are made. Moreover, the LQG-LTR control law is designed and analyzed. How to tune the parameters is discussed. The results of simulation and experiment show that, LQG-LTR improves the robustness and dynamic performance significantly.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"15 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120981691","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}

This interference causes large surplus torque in the loading system, which affects the loading accuracy and the dynamic performance greatly. In this paper, in-depth theoretical analysis of the electro-hydraulic load simulator has been presented, the mathematical model of surplus torque has been built up, all kinds of factors which affect the surplus torque have been discussed, simulation and experiments have been made to testify the results. It can be concluded that the velocity disturbance from steering gear acting on the loading system is the key factor which brings about the surplus torque. Proper selection of load system's structural parameters, such as load stiffness, motor displacement and effective volume, is crucial to the high performance electro-hydraulic load simulator's implementation.","PeriodicalId":241423,"journal":{"name":"Proceedings of 2011 International Conference on Fluid Power and Mechatronics","volume":"23 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":"124875491","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 control algorithm based on fuzzy logic control algorithm combined with PID control algorithm is established.
