This paper focuses on the clamping force control strategy of an electro-mechanical brake (EMB) system. In this study, a three-closed-loop control system is proposed. The clamping force loop utilizes a fuzzy PID control algorithm, which combines the advantages of fuzzy control and PID control to improve adaptability and robustness to changes in clamping force. The speed loop adopts the traditional PID control algorithm, which ensures stable speed control through feedback adjustment of speed error. The current loop utilizes hysteresis loop control to achieve accurate current control and anti-disturbance performance by adjusting the hysteresis loop width and compensating for current error. Simulation results demonstrate that the proposed three-closed-loop clamping force control method can quickly achieve the target braking clamping force.
