    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.
