Tracking Control of Networked Multiple Linear Switched Reluctance Machines Control System Based on Position Compensation Approach

摘要

This paper proposes the precise tracking control for the multiple linear switched reluctance machines (LSRMs) with network-induced time delays by using the motor positions compensation method. Considering the mutual position disturbances among the multiple motors, two network topologies are proposed for the multiple LSRMs control system. In order to improve the tracking precision, the motor position signals are used to compensate the tracking errors among the three motors. The encoders-to-controller and the controller-to-actuator time delays are modeled as a discrete-time Markov chain which denotes the whole random time delay step for the closed-loop control system. The stability conditions and the tracking controller design method for the networked LSRMs control system are proposed by using Lyapunov theory and the inequality techniques. Several groups of experimental results are presented to verify the effectiveness and practicability of the proposed method for the networked multiple LSRMs control system.
