数字锁相调速系统中的最少拍控制

GONTROL OF DIGITAL PHASE-LOCKED-LOOP(DPLL) VELOCITY SYSTEM WITH THE DEADBEAT RESPONSE

本文将一般数字控制系统的最少拍控制律推广到数字锁相(DPLL)调速系统,考虑了阻力矩的作用。推出的控制过程规律虽比原结果多了一至二拍,但为锁相调速系统中更符合实际的最少拍控制律。

When applying the control law with the deadbeat rey-ponse as described in general books to velocity control systems withDPLL, we must also consider the effects of the resistance moment.Thispaper gives the result in which the resistance moment is considered.Though the process by this law is one or twn step longer than the pre-viots, this law is more adaptive to real conditions.
