摘要: 为了提高汽车电子机械制动系统的动态响应特性及可靠性,在分析了电子机械制动系统工作原理的基础上,使用Matlab/Simulink和AMESim软件分别建立了永磁同步电机磁场定向控制仿真模型和机械执行机构物理模型,提出了基于期望夹紧力的转角预测前馈和模糊PID反馈的闭环控制策略。基于AMESim与Matlab/Simulink软件搭建联合仿真平台,采用阶跃信号、方波信号和梯形信号分别模拟车辆紧急制动、频繁制动和常规制动工况,进行仿真对比分析,验证了该夹紧力闭环控制策略的有效性。仿真结果表明,相比传统方法,该策略显著提高了系统的动态响应速度和控制精度。

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
