The PID Control for Electro-hydraulic Servo System Based on Orthogonal Test
To increase control precision and improve dynamic characteristic of electro hydraulic position servo system, a method of processing data called orthogonal test that usually adopted in chemical experiment is applied. After parameters are ensured, the Critical gain Kv of the open-loop system is determined by the Stability, then the factors are determined and the orthogonal table is constituted to try out In the end, the dynamical characteristics of the system are simulated by SIMULINK software. Thus the optimum PID parameters can be achieved. Through the method above, we can avoid a lot of complex trials which determine PID parameters and get more efficient. It is shown by simulation that the PID rectification for electrohydraulic position servo system using orthogonal test increases fairly control precision, rapidity of step response and make the quality of the control system best.
