利用最优输出反馈的鲁棒调节器设计方法

本文提出了在阶跃型及斜坡型参考输入及干扰下,鲁棒调节器的一种设计方法.这种方法 是将稳定补偿器的设计转化为输出反馈二次型调节器的设计.利用梯度矩阵的表达式,就可 以采用一般单参数寻优方法获得一个简单的调节器.对燃气轮机模型的仿真研究说明了这种 调节器的鲁棒性.最后对这一方法作了扼要讨论.

A Design Method for Robust Controller Using Optimal Output Feedback

A robust controller design method for a system under step or ramp reference inputs or disturbances is presented in this paper. The design problem of a stabilizing compensator is converted into a linear quadratic problem with the output feedback. The explicit expression of the gradient matrix allows the use of the optimization technique with a single parameter. The simulation study of a gas-turbine model demonstrates the robustness of the controller. A brief discussion is also given.
