基于Stribeck摩擦模型的模糊PID控制在伺服系统中的应用

由于采用常规PID算法很难跟踪上基于Stribeck摩擦模型的伺服系统的输入信号,本文采用了模糊PID与传统PID控制相串联的方法,以飞行模拟台伺服系统背景进行仿真实验研究,结果表明,该方法设计简单,能对具有带摩擦的伺服系统进行有效控制,具有较强的鲁棒性和抗干扰性能,并明显优于常规PID控制的性能。

Application of the Servo System with Fuzzy PID Control that Base on Stribeck Friction Model

Because the routine PID arithmetic is difficult to run after the input signal of the servo system that base on the Stribeck friction model, this design adopts fuzzy PID and routine PID in series, we use the flight simulator servo system adjust as background to making a emulational research, the result shows that, this simple design arithmetic can treat well with the servo system that base on the friction model, in addition, it also has a strong robustness and anti-interference, so its performance is more better than the routine PID control.
