摘要: 为解决常规LQG/LTR控制器中存在的参数值过大问题, 提出了非完全恢复的LQG/LTR设计方法, 并从控制系统中零极点关系的角度, 阐述了该设计方法降低控制器参数数值的机理.将该方法应用于航空发动机控制系统设计中.仿真表明, 该方法不但有效地抑制了控制器的参数值过大, 且相对于常规LQG/LTR设计方法具有更理想的控制效果.

Abstract: To solve the problem of excessively big parameter value in the conventional LQG/LTR controller,a design method was proposed for non-fully recover LQG/LTR.The principle for reducing the controller parameter value was explained from the perspective of system's zero-pole relationship.This method was applied to design the aeroengine control system.Simulation results indicate that this method could suppress effectively the parameter value of controller,but also present more satisfactory performance than conventional LQG/LTR design method.
