非线性PID控制器的计算机辅助设计

Nonlinear PID Controller by CAD

本文采用了一种根据系统输出偏差修改控制参数的非线性PID控制器 ,并使用MATLAB的非线性控制系统设计工具箱 (NCD)和优化工具箱提供的优化函数进行控制参数的快速寻优 ,提高了设计效率 ,仿真设计表明该方法是可行的。

The design method of nonlinear PID controller whose control parameter can be varied by system output error is proposed in this paper. And using the optimization function supplied by NCD toolbox and optimization toolbox based on MATLAB, the rapid optimization of control parameter can be conducted, thus the efficiency of design is greatly improved.
