基于采样控制的离散方法,提出了最速跟踪微分器的一种新型离散形式.去掉了原有最速跟踪微分器离散系统中的一个零阶保持器环节,并推导了新型离散系统的最速控制综合函数.与最速跟踪微分器的原有离散形式相比,所提出的离散形式不但减少了信号滤波中的相位延迟,且得到的最速控制综合函数表达式更为简洁.
A new discrete form of optimal tracking differentiator is proposed based on the discrete method of sampling control. A zero-order holder in traditional discrete system of optimal tracking differentiator is left out, and the optimal control synthesis function of the new discrete system is deduced. Compared with the traditional discrete form of optimal tracking differentiator, not only the phase delay in signal filtering is reduced, but also the optimal control synthesis function is more abbreviated.
