【摘要】 在EPS开发过程中,经常出现系统不稳定的状况,如助力系数的增大、电流环延时时间的增长等都会使得系统趋于不稳定。为进一步提高EPS的稳定性,本文提出了一种基于转矩微分的相位补偿策略。仿真及台架试验结果表明,所采用的相位补偿策略能有效改善EPS的稳定性。
【Abstract】 In the development of electric power steering system(herein after EPS),certain unstable phenomenon appears frequently.With the increases of assistant gain and delay constant of current-loop,the system tends to unstable.As for further improving the control strategies of EPS system to increase its stability,phase compensation based on torque differentiation is proposed in this paper.Some simulation and rig tests have been conducted.The results show that the proposed phase compensation strategy could effectively improve the EPS stability.
