用MATLAB设计鲁棒PID压力控制器系统

Design for a Robust PID Pressure Controller with MATLAB

利用可重复执行的交互式MATLAB软件,给出了鲁棒PID压力控制器的设计方法。研究结果表明,所设计的PID压力控制器的调节时间T_s≤0.5s,当输入为阶跃信号时,系统能达到ITAE最优。仿真结果表明,通过串联一个增益放大器,当C_0在0.1～10范围内变化时,所设计的PID压力控制器具有很强的鲁棒性。

A robust PID pressure controller was designed with MATLAB software. The results show that the adjusting time of the designed controller is less than 0. 5 s and the system satisfied the ITAE optimum condition when the input signal is step one. When a gain amplifier is in series with the designed system,the emulation results show that robustness of the designed controller is kept when the parameter C0 changes from 0. 1 to 10.
