Partial delay dependent disordering controller and establishment method thereof

Abstract

The present invention discloses a partial delay dependent disordering controller and an establishment method thereof. The partial delay dependent disordering controller includes a controller on the basis of a new operation mode (NOMs) and a controller on the basis of a non-fragile method. The controller on the basis of the new operation mode (NOMs) has an expression as follows: u(k)=K1-bar(r<k>)x(k)+K2-bar(r<k>)x(k-d), wherein, K1-bar(r<k>) is a controller grain, K2-bar(r<k>) is a system state, and the time delay d>=0. The controller on the basis of the non-fragile method has an expression as follows: u(k)=(K1-bar(r<k>)+DeltaK1-bar(r<k>))x(k)+(K2-bar(r<k>)+DeltaK2-bar(r<k>))x(k-d), wherein, K1-bar(r<k>) is a controller grain, x(k) is a system state, time delay d>=0, and DeltaK1-bar(r<k>) and DeltaK2-bar(r<k>) are controller grain disturbances.

Description

technical field [0001] The invention relates to a controller, in particular to a partially time-delay-dependent out-of-sequence controller and its establishment method. Background technique [0002] Time-delay problems exist in many real dynamical systems, chemical systems, such as heating systems, biological systems, network control systems (NCSs), telecommunications, and economics. As we all know, in these practical systems, the existence of time delay often degrades the performance of the system, and even leads to instability. By studying the stabilization results of various types of time-delay systems, it is found that the stabilization related to state feedback control is mainly obtained by controllers with no time-delay or only with time-delay. When designing stabilizing controllers for systems with time-delays without time-delays, an idealized assumption that the relevant system states should be available online is necessary. Instead, it is assumed that there is alw...

Problems solved by technology

Although the use of a shared communication network has great advantages such as low cost, reduced weight and power requirements, easy installation and maintenance, and high reliability, the introduction of the communication network makes the analysis and synthesis of the corresponding system very complicated, which also brings Comes with many interesting and challenging problems such as network latency, packet loss, quantization and out-of-sequencing

At present, there is no good design method for partial time-delay-dependent out-of-sequence controllers for time-delay systems, all these facts will promote and promote the completion of the patent of this invention
