摘　　要：针对压电陶瓷精密位移控制系统,分析了PID控制系统和模糊控制系统的控制性能,在自适应模糊PID控制的基础上,通过控制过程中对模糊控制器论域的改变,形成自适应变论域模糊控制系统。对模糊控制器论域的变化进行了分析和制定,并针对位移系统建立了数学模型,将变论域模糊控制器应用于压电陶瓷传感器中,用Matlab进行仿真。试验结果表明,变论域模糊控制器比自适应模糊控制器响应速度快、抗干扰能力强、鲁棒性好。Based on the piezoelectric ceramic precision displacement control system,the property of controlling the whole system with PID ＆ fuzzy algorithm is analyzed.By changing the universe in fuzzy controller with adaptive fuzzy PID control,the variable universe adaptive fuzzy PID control system is established. The mathematic model of displacement system is formulated and variable universe adaptive fuzzy eontrol system is embedded in PZT control system through analyzing the variation of fuzzy controller.Through simulation with Matlab,the results show that the variable universe adaptive fuzzy PID controller has fast dynamic response, strong anti-interference ability and robustness.
