Papers by Keyword: Sampling Control System

Abstract: The paper built electro-hydraulic position closed-loop sampling control system based on PLC, established mathematical model of this system by applying theory of sampling control and determines the range of the sampling period T under the stability of the system according to system stability theory. Then carried out simulation analysis and experimental verification in the range of T, provided with the method determined the range of sampling period. The results showed that simulation results of this model were consistent with the actual operation of the system , the method and sampling period be chosen have some practical significance.
