Intelligent-PI controller for electro-hydraulic system
2016 4th International Conference on Control Engineering & Information Technology (CEIT), 2016Electro-hydraulic actuators have been widely applied in industry with position or pressure control. Nevertheless, the conventional linear control technology is not able to satisfy the requirement of improving the control precision due to the nonlinearities of hydraulic systems. This paper presents two control strategies based on intelligent-PI in order

Electro-hydraulic servo system with predictive control
2009 4th IEEE Conference on Industrial Electronics and Applications, 2009Propellent is a primary propulsive power source of the space navigation and missile weapon. In order to safely produce, transform and use it, its characteristics of friction sensitivity must be known very well. The results of test and analysis show that the precision of load force is the most important factor which affects the testing results ...
