Problems solved by technology

[0006] On the other hand, since disturbances are unavoidable, it is necessary to analyze the anti-disturbance performance of NCS with disturbances, l 2 -l ∞ Performance indicators are proposed to analyze the influence of external disturbances, and are mainly used to solve many control problems. In networked control systems, l...

Abstract

The invention discloses a switching system method and system for 12-1[infinity] control based on a network control system, a controller and a control method. The method comprises the following steps:establishing a continuous time network control system model; discretizing the continuous time network control system to establish a discrete time sampling system; according to the number of lost packets, modeling a sampling system into a discrete time switching system, designing a sampling controller for ensuring the index stability and 12-1[infinity] performance of the system. Due to the design of the steps, a plurality of complex systems which cannot be described by a single model can be described, the stability of the system under the condition of packet loss can be researched, and externalinterference can be suppressed.

Description

[0001] 1. Technical field [0002] The present invention relates to a switching system method and system, controller and control method, especially a network-based control system l 2 -l ∞ A switching system method of control and a system, a controller and a control method. [0003] 2. Background technology [0004] In the network control system, due to the limited network bandwidth used for information transmission, each node must compete with each other to obtain network resources, and the limited network bandwidth causes the nodes to lose data packets due to competition failure. In the network, packet loss It is inevitable, especially in wireless networks, data packet collision or node competition failure will lead to data packet transmission failure, therefore, packet loss has become an important factor that must be considered in the process of network control system analysis and design. [0005] The switching system method is an effective method to solve the packet loss p...
