A novel Fuzzy-Sliding Mode Controller for Antilock Braking System

In this paper a hybrid controller for wheel slip ratio control has been designed base on a quarter vehicle model. The proposed controller is a combination of a sliding mode controller (SMC) with a fuzzy controller to improve sliding mode controller efficiency. Three different sliding mode controllers are compared and the best one of them combined with a fuzzy controller to increase controller performance by eliminating the time responses oscillation. Three different road conditions have been chosen base on a look-up table. Simulation results show good performance of the proposed controller for different road conditions.
