Improved Position Tracking Performance of Electro Hydraulic Actuator Using PID and Sliding Mode Controller

This paper focuses on the position control of low-velocity servo controlled electro hydraulic actuator system in order to increase the system productivity. To overcome the nonlinearities and uncertainties caused by friction and internal leakages, an efficient sliding mode control (SMC) is designed based on the selection of appropriate sliding surface and control law. The solution is a model-based position control and it is shown that the...
