High Order Sliding Modes For Vehicle Suspensions Via Optimized Super Twisting Algorithm
A high order sliding mode controller, based on super twisting algorithm, is designed in this study for vehicle
active suspensions. High order sliding mode is preferred since the first order sliding mode controller suffer from chattering
in control signal. The controller parameters are determined using a multi-objective genetic algorithm. Designed controller is
applied to a quarter car active suspension system, where it is aimed to improve the ride comfort of passengers. First order
sliding mode controller is also applied for comparison. Numerical results indicate the outstanding performance of the
designed high order sliding mode controller.
