A Fuzzy Sliding Mode Controller for an Air Spring Active Suspension

Abstract:

Due to nonlinearity, preload-dependent spring force and parameters uncertainty in air spring, it is difficult to control this suspension system. To achieve a desired performance, a fuzzy sliding mode controller (FSMC) has been designed to improve the passenger comfort and manipulability of vehicle, in which the fuzzy adaptive system is used to deal with the nonlinearity and uncertainty of the air suspension. A normal linear suspension model with an optimal state feedback control is designed as the reference model. The simulation results show that this control scheme is more effective and robust in the vibration isolation of the vehicle body than is the conventional sliding mode controller (CSMC).
