Using Stabilizer Dynamic Pre-Compensator to Design Robust Controllers for an Unstable MIMO System

摘要

This paper addresses the problem of designing LQG/LTR controllers for unstable multivariable systems. Its main proposal is to design a stabilizer dynamic pre-compensator to stabilize the system before designing the final LQG/LTR controller. This approach overcomes the problems that the This paper addresses the problem of designing LQG/LTR controllers for unstable multivariable systems. Its main proposal is to design a stabilizer dynamic pre-compensator to stabilize the system before designing the final LQG/LTR controller. This approach overcomes the problems that the original procedure can not avoid when it deals with unstable systems, but the order of the overall controller gets increased.
