Simulation results show that,if the best-fit slip rate is known,PD control slip rate control algorithm is the best,but in the actual application it difficult to determine best-fit slip rate, so logic threshold algorithm is more practical.
仿真结果分析表明,在已知路面最佳滑移率时,PD控制滑移率算法的控制效果最好,但在实际应用中最佳滑移率的判断较难所以逻辑门限值算法较为实用。
