基于改进PSO算法的拖拉机驱动防滑PID控制策略
PID control strategy of tractor driving anti slip control based on improved PSO algorithm
摘要
Abstract
In order to improve the trafficability of the non-road vehicles such as tractors in normal driving and working stages, this paper studied the ASR control strategy.Based on the combination of MATLAB/Simulink and Carsim,it established a trac-tor simulation model.This strategy updated the target slip rate in real time with the new method of road surface identification and used improved particle swarm optimization algorithm to adjust PID control parameters adaptively.Based on different pave-ment,a series of simulation experiments’results show that the target slip rate is changed with the vehicle driving and finally e-qual to the optimal slip rate of the pavement;based on the improved PSO algorithm,it adjusts the PID parameters rapidly,and the speed of the tractor slip rate to the target value is fast,with an average of about 1 .5 s;when driving in the docking road,it can effectively inhibit tractor from high adhesion coefficient road have just entered the low adhesion coefficient road slippery conversion rate soared,in high and low attachment coefficient road stability time are 2.63 and 1.55 seconds.关键词
