指出了分析采样控制系统通常所用方法存在的问题和矛盾。给出了包含有冲量比例系数(采样开关每次闭合持续时间)τ的采样函数Z变换定义,以此为基础,讨论了采样控制系统的脉冲传递函数。说明这种做法可以解决前进方法存在的问题和矛盾。
Pointed out the problems and contradictions existing in the method of analyzing sampling control system. The definition of Z transform of sampling function including impulse proportional coefficient (the duration of each closing of sampling switch) τ is given. Based on this, the pulse transfer function of sampling control system is discussed. This shows that this approach can solve the problems and contradictions in the way forward.
