液压位置伺服系统的模糊PID控制研究

Study on Fuzzy PID Control of Hydraulic Position Servo System

针对液压位置伺服系统中参数时变和非线性等特点，使用模糊PID控制算法实现对PID参数的在线自调整。Matlab仿真表明，与传统PID控制相比，模糊PID控制系统具有超调小、稳态精度高、鲁棒性强等特点。

Considering the characteristics of time-varying parameters and nonlinearity of the hydraulic position servo system, the Fuzzy PID control algorithm is applied to realize the self-regulation online for the PID parameters. The simulation results based on Matlab show that the Fuzzy PID control system is of smaller overshoot, higher steady-state precision and stronger robustness than the traditional PID Control.
