Özet

A novel decoupled Multi-Input-Multi-Output Model Free Control strategy is presented in this paper to improve the performance of an active suspension system implemented on a half car model. To damp vibrations generated by road excitation, an algebraic online compensator was integrated in the structure of a classical PID controller to avoid the impact of unpredictable disturbances. The key element of the proposed technique is a non-asymptotic observer that can avoid the use of statistical conventional techniques. Furthermore, the advantage of easy implementation is achieved where only two accelerometers are sufficient and adequate. A comparison with classical PID and LQR is provided to demonstrate the improvement made by the proposed scheme.
