Abstract The possibility to enhance the stability and robustness of electrohydraulic brake (EHB) systems is considered a subject of great importance in
the automotive field. In such a context, the present study focuses on an actuator
with a four-way sliding valve and a hydraulic cylinder. A 4-order nonlinear mathematical model is introduced accordingly. Through the linearization of the feedback law of the high order EHB model, a sliding mode control method is
proposed for the hydraulic pressure. The hydraulic pressure tracking controls
are simulated and analyzed by MATLAB/Simulink soft considering separately
different conditions, i.e., a sine wave, a square wave and… More >
