摘要
针对车辆防抱死制动系统(ABS)控制算法的选择及适用问题,提出控制算法的选择应与车辆结构及实际性能要求相结合的方法,可以充分发挥不同ABS控制算法的优越性;使用Matlab/Simulink仿真软件建立车辆单轮制动模型,针对不同的初始制动车速和质心位置向后移动两种情况,分别采用变结构滑模控制和PID控制进行了制动过程的模拟与研究;仿真结果表明,当车辆结构及制动条件发生变化时,两种控制方式都能很好的完成制动,且各有优点,可以满足不同制动性能的需求。
The structure and use of the vehicle are different , and every kinds of ABS control algorithm have their own characteristics, so the point that the choice of ABS control algorithm should be combined with vehicle structure and the actual performance are proposed. By considering the different initial speed and the change of the vehicle＇s mass center position, the single wheel brake model of vehicle is built by using Matlab/Simulink, and it is used to the simulation research of the vehicle braking process which is controlled by PID or Sliding mode. The simulation results show that the two control methods are all able to complete the task and each of them has its own advantage , the control system could meet the requirements of any users.
