In this thesis, a new idea of clamp force control is used to attenuate the judder vibrations in the electromechanical braking system caused by changing the brake torque. First, a Fairly accurate nonlinear dynamic model that includes the electrical and mechanical components of an electromechanical braking system is defined and presented in MATLAB software. after that, a simple nonlinear model is defined for the compensator design, and based on that, a compensator model is designed by sliding mode control method for active attenuation of judder vibrations. Finally, the necessary tests to evaluate the performance of the compensator are selected and the performance of the compensator on the nonlinear model in the test conditions is investigated. The results obtained from this thesis have shown well that by using a sliding mode compensator, it is possible to evaluate the wall at the source of the electromechanical braking system at a low cost and to the root mean square error track at high speeds up to 45% decreased. In addition, this method, like adaptive compensator, does not require measuring the angular position of the disk, and also does not require instability defects at high speeds and high sampling rates when implemented in microcontrollers, such as linear parameter-varying compensators after discretization.
