Abstract :
Sampling period is an important parameter with aspect influence in digital control system. In this paper, based on a multi-input -multi-output system and the method of dynamic matrix predictive control, a model of multi-rate output was established; Using genetic algorithm to realize the optimization of sampling period, and the simulation for a speed-coupling system indicated that, when the sampling-period are selected properly, the stability and system performance with multi-rate output system are better than other output periods.
