Problems solved by technology

[0005] In order to overcome the shortcomings of existing networked control methods that cannot be applied to systems with uncertain parameters and poor robust performance, the present invention introduces a dynamic event trigger mechanism, and proposes a networked system with an uncertain parameter dynamic event trigger mechanism. The control method, based on Lyapunov stability theory and linear matrix inequality technology, gives a state feedback controller design method under the dynamic event trigger mechanism, which reduces the number of network data transmissions and can also enhance the robustness of the system

Abstract

A robust control method for a networked system based on a dynamic event-triggering mechanism, comprising the following steps: first, considering the network delay, the networked control problem of an inverted pendulum is modeled into a state space model with parameter uncertainty; second In the first step, based on the Lyapunov stability theory and the linear matrix inequality technique, the sufficient conditions for the system to be asymptotically stable and to satisfy the robust performance index are obtained. In the third step, the design method of the state feedback controller under the dynamic event-triggered mechanism is given. The invention provides a robust control method for a networked system based on a dynamic event trigger mechanism, which can reduce the number of network data transmissions and enhance the robust performance of the system.

Description

technical field [0001] The invention belongs to the field of networked control, and designs a method applied in networked control to reduce network load and energy consumption, reduce the number of data transmissions, stabilize the system and enhance the robust performance of the system. Background technique [0002] Nowadays, with the rapid development and wide application of network technology, the trend of control system to be networked, distributed, intelligent and comprehensive is becoming more and more obvious. In a networked control system, each unit of the system is connected through a public network, and signals are transmitted and exchanged through a communication network. The communication mode of information exchange through the network also brings new opportunities and challenges to the analysis and design of networked control systems, such as network delay, bandwidth limitation, signal quantization, disturbance, packet loss rate and other issues, among which th...
