自动化专业英语课后译文
下纠正速度误差，直到速度偏差减小且限流装置退出饱和状 态。现在，速度误差在Ia小于最大允许电流值的情况下进纠 正。 负的速度误差将设置负的电流参考值Ia* 。因为电机电流 不能反向，负的Ia*是没用的。然而，它将“掌管”PI控制器。 当速度误差变正时，“被掌管”的PI控制器将花费较长时间 响 应，造成控制中不必要的延迟。因此，对于负的速度误差， 限流器的电流给定值被设为零。
c(t ) L1 c( s) css (t ) ctr (t )
式中css(t)是稳态响应，ctr(t)是暂态响应。如果系统是不稳定的， 就将没有稳态响应，只有暂态响应。

电路
di uL dt
(1-1A-2)
式中 di/dt = 电流变化率， 安培/秒； L = 感应系数， 享利。 电容两端建立的电压正比于电容两极板上积累的电荷q 。 因为电荷的积累可表示为电荷增量dq的和或积分，因此得到 的等式为 ： 1 (1-1A-3) u dq
(由于s 是复变量，亟待和零点可能是复数，KZ(s)/P(s) 是复变函数，
因此可用一个有幅值和与其相关的角度或叫幅角的矢量来表示。在公式(23A-2)右边的每一个分解因子可被看作)
