MIMO系统的H_∞PID控制器的参数设计

The Design of H_∞PID Controller of MIMO Systems

应用先进的Ｈ∞控制理论，提出一种用ＬＭＬ方法设计多输入－多输出系统的ＰＩＤ控制器 参数的方法．用该方法设计出的控制器是由多个单输入－单输出的ＰＩＤ控制器组成，而不是多变 量耦合的ＰＩＤ控制器．试验证明，用该方法设计出的Ｈ∞ＰＩＤ控制器控制效果较好，鲁棒性较强．

This paper presents a design approach for tuning PID controllers of MIMO systems by solving the corresponding linear matrix inequalities (LMI) based on H∞ control theory The designed controller is not a multi-variable PID controller, but composed of several SISO PID controllers. The simulation results show that the control performance of the resulting system is very good and the robustness is very strong.
