Ensuring the stability and constant controlled parameters of the output of a multi-input and multi-output (MIMO) networked control system under interference is an important research topic in the field of automatic control. Based on the state feedback of linear systems, a linear quadratic (LQ) control method that maintains zero output error is proposed. The stability conditions of the closed-loop system are given. By using integral control and finite-time LQ tracking control strategy, the stability of the output of the closed-loop control system is protected. Simulation results show that this control strategy can effectively reduce the system's convergence time and ensure output stability under interference.

摘要

Ensuring the stability and constant controlled parameters of the output of a multi-input and multi-output (MIMO) networked control system under interference is an important research topic in the field of automatic control. Based on the state feedback of linear systems, a linear quadratic (LQ) control method that maintains zero output error is proposed. The stability conditions of the closed-loop system are given. By using integral control and finite-time LQ tracking control strategy, the stability of the output of the closed-loop control system is protected. Simulation results show that this control strategy can effectively reduce the system's convergence time and ensure output stability under interference.
