Three optimal controllers for a multivariable active suspension system are designed and compared. The main idea of these controllers is to achieve optimal stability margins and good performance in step response of the system. LQG/LTR method is an optimal design technique based on shaping and recovering open-loop singular values while LQR is a technique based on pole placement methods which characterize the optimal pole location. LQG/LTR controller has been applied to the suspension system and the results have been compared by pole placement and LQR methods. Results show that LQG/LTR method is prominent and has the priority of application rather than the other compared techniques.
