Abstract:

For the chattering problem of variable structure control based on exponential reaching law,a variable structure control based on improved exponential reaching law has been proposed and applied in the design of ABS controller.MATLAB/Simulink modeling and simulation have been employed to verify the effectiveness of the proposed controller on single road and variational road.The results show that the variable structure control based on improved exponential reaching law can effectively reduce the chattering and keep the robustness and quick response capability of the conventional variable structure control.

Key words: anti-lock braking system, variable structure control, improved exponential reaching law, chattering
