Abstract

Abstract: In order to improve the dynamic response characteristics and reliability of the automotive electromechanical braking system,the working principle of the electromechanical braking system was analyzed. Matlab/Simulink and AMESim software were used to establish the simulation model of magnetic field-oriented control and the physical model of mechanical actuator of permanent magnet synchronous motor,respectively,and a closed-loop control strategy based on expected clamping force to predict feedforward and fuzzy PID feedback was proposed. Based on AMESim and Matlab/Simulink software,a co-simulation platform was built,and step signals,square wave signals and trapezoidal signals were used to simulate the emergency braking,frequent braking and conventional braking conditions of the vehicle,respectively,and the effectiveness of the closed-loop control strategy of clamping force was verified by simulation and comparative analysis.The simulation results show that compared with the traditional method,the proposed strategy significantly improves the dynamic response speed and control accuracy of the system.

Key words: electromechanical braking system, co-simulation, corner prediction, fuzzy PID control
