Research on Fuzzy PID Control of Electro-hydraulic Servo System Based on MATLAB-AMESim Joint Simulation |
| |
| Abstract: | Electro-hydraulic servo system is widely used in industry. A simulation model of the system was built based on the com-bined use of MATLAB and AMESim to deal with the problem that mathematical models could not accurately reflect the nonlinear system of hydraulic servo system. The design process of the fuzzy PID was described. The performance of PID control and fuzzy PID control were analyzed based on simulations. The results show that the fuzzy PID has improved dynamic and static performance and the system has higher robustness and anti-jamming ability. |
