摘要
为改善汽车制动控制中由于机械惯量不足而引起误差大的缺点,提出了制动器试验台驱动电流控制方法.通过采用机械惯量电模拟的方法,用驱动电流控制来追加影响补偿模拟系统对真实系统的偏离,让模拟系统的转速、角速度逼近于理想化真实系统的值,并用能量误差作为评价指标.经MATLAB仿真试验证明,该控制方法误差小且算法简单,抗干扰性好,鲁棒性强,可以缩短制动距离,控制效果较为理想.
In order to improve relatively severe weakness of automobile braking controlling due to insufficient mechanical inertia,a new method of brake test drive current controlling is proposed,using drive current control to add the deviation caused by simulation system compensation compared with the real system,the speed,angular velocity of simulation system is approximate to values of real system,energy error is regarded as an evaluating indicator.It showed that in MATLAB simulation experiments,the control method has less error,simple algorithm,and good disturbance and great robustness,it can shorten braking distance and the effect of controlling is more ideal.
