摘要
文章依据典型的线性二自由度汽车模型结合freescale智能小车的实际转向系统建立数学模型,推导出微分方程,采用比例微分控制(PD)策略,并结合系统模型运用MATLAB进行仿真。采用比例微分控制(PD)策略对小车的转向系统的信号延时进行改进,对稳定性等方面也进行改善,达到预期的优化目的。
Based on the typical linear two degrees of freedom vehicle model with Freescale intelligent car of the actual steering system to establish the mathematical model, differential equations are derived that, proportional differential control （ PD ） control strategy, combined with the use of MATLAB simulation system model. The simulation results show that the proportional and differential control （ PD ） strategy on vehicle steering system improved the stability of signal delay, achieved the desired optimization objective.
