Vibration control of vehicle active suspension using sliding mode under parameters uncertainty

Popis výsledku v původním jazyce

This paper introduces a theoretical investigation of active vehicle suspension system using sliding mode control (SMC) algorithm to enhance the ride comfort and vehicle stability under parameters uncertainty. SMC algorithm is a nonlinear control technique that regulates the dynamics of linear and nonlinear systems using a discontinuous control signal. The proposed control algorithm forces the suspension system to follow the behavior of the ideal sky-hook system behavior. A mathematical model and the equations of motion of the quarter active vehicle suspension system are considered and simulated using Matlab/Simulink software. The proposed active suspension is compared with the passive suspension systems. Suspension performance is evaluated in both time and frequency domains, in order to verify the success of the proposed control technique. Also, uncertainty analysis due to the increased of sprung mass and depreciated of spring stiffness and damping coefficient is also investigated in this paper. The simulated results reveal that the proposed controller using SMC grants a significant enhancement of ride comfort and vehicle stability even in the existence of parameters uncertainty.
