This paper suggests an adaptation scheme for robust control of Electronic Wedge Brake (EWB) and estimation of pad friction-coefficient. The Electronic Wedge Brake is highly energy-effective as it uses self-reinforcement. But accordingly, it can be sensitive to the parametric variation, particularly to the pad friction-coefficient. The suggested scheme reduces the effect of the variation of pad friction-coefficient on system robustness and provides a way of estimation of the friction-coefficient in real time. The series of simulation results verify the performance of suggested control scheme.
