基于参数整定PID控制的电子机械制动执行器控制方法研究
Control methods for electro-mechanical brake actuators based on parameter tuning PID control
摘要
Abstract
The rapid advancement of vehicle electrification has driven significant innovation in brake-by-wire systems,rendering conventional hydraulic braking systems inadequate to meet the evolving demands of new energy vehicles.In this context,electro-mechanical braking(EMB)has emerged as a pivotal development direction in smart vehicle braking technology.This paper analyzed the typical structure of an EMB actuator featuring a motor-planetary gear-ball screw configuration.A three-stage closed-loop control simulation model was established within the MATLAB/Simulink environment,and the braking performance of the EMB actuator was validated through co-simulation with CarSim and MATLAB/Simulink.Building upon this foundation,a control method for the EMB actuator was further developed based on the three-stage closed-loop strategy,incorporating a novel brake clearance control strategy dependent on vehicle speed.By varying the target clamping force at the input of the EMB control system,the dynamic behaviors of clamping force,ball screw nut displacement,and motor rotational speed were systematically analyzed.For the proportion integration differentiation(PID)control loop governing clamping force,parameter tuning of the PID controller was implemented to optimize overall system performance.Simulation results demonstrate that fixed-gain PID control exhibits inherent limitations in achieving precise target clamping force regulation;however,the proposed parameter tuning approach significantly enhances control accuracy,ensuring close alignment between actual and desired clamping forces.关键词
