Switching system control method with controlled quantity anti-shake and interference suppression performance

Abstract

The invention discloses a switching system control method with controlled quantity anti-shake and interference suppression performance, relates to the technical field of switching system control, and aims to solve the problem that an actuating mechanism of a controlled object is damaged due to large-amplitude jump of a control signal in an existing switching system. The technical key points are that the method comprises the steps: establishing a discrete time switching linear system model; establishing a segmented controller structure; establishing an anti-shake control problem of the switching linear system with H infinity performance guarantee; proposing a large-range consistent asymptotic stability condition of the discrete time switching system with an anti-shake continuous residence time switching signal; carrying out the anti-shake controller solving with stability guarantee on the discrete time switching linear system under the continuous residence time condition; proposing large-range consistent asymptotic stability and l2 gain conditions of a discrete time switching system with an anti-shake continuous residence time switching signal; and carrying out anti-shake controller solution with H infinity performance guarantee. The anti-shake controller designed based on the method has interference suppression performance.

Description

technical field [0001] The invention relates to the technical field of switching system control, in particular to a switching system control method with the performance of control quantity anti-shaking and interference suppression. Background technique [0002] Switching system theory and switching control methods have achieved rich results since their establishment, and have been widely used in actual physical systems such as aircraft control systems, robot motion control systems, and process control systems. As one of the notable features of a switched system, switching behavior is generated spontaneously due to the change of the dynamic model of the controlled object on the one hand, and artificially introduced switching strategies to improve the control performance of the system on the other hand. However, due to the existence of switching behavior, the control signal of the switching system is more prone to jitter, that is, a large change, which will lead to system perf...
