In this paper, a practical Identification strategy is applied to the optimal design of fractional-order iterative learning control (FOILC). The initialized fractional-order gray-box system with commensurate order or non-commensurate order is identified by using the fractional-order iterative learning Identification and the least square or instrumental variable method. The optimal Dα-type FOILC is...
The problem of L1-induced performance analysis for continuous positive systems with time-delay is investigated in this paper. At first, we propose a integral method to compute the value of the system L1-induced norm, and the relationship between the transfer function and L1-induced norm of such systems is obtained. Then, the necessary and sufficient condition is given to ensure that such systems are...
Dynamical systems in the real world are always subject to various disturbances. This paper studies the dynamics of delayed discrete-time linear systems with decaying disturbances. It is first shown that if an unforced linear system is exponentially stable, then the disturbed system has a dynamical property like the exponential stability if the disturbance decays at an exponential rate, and has a dynamical...
In this paper, we investigate the network-dependent hybrid controller design for a class of networked switched linear control systems. Sampling and network-induced delay cause the asynchronous motions between switched subsystems and the candidate controllers in both the state measurement and the switching signal. We rewrite the original networked switched linear systems by sampled asynchronous switched...
In this paper we investigate the cooperative output regulation problem of linear multi-agent systems with a switched exosystem which is assumed that some subsystems are Hurwitz stable, some are neutral stability, and the others are unstable. We will deal with two difficulties in the paper. One is the complexity of the switched exosystem trajectory. The other is the limited information exchanges of...
The paper considers the robust H2 state feedback control design for a class of linear uncertain systems with input quantization. The uncertainties are assumed to be time-varying, unknown, but bounded. The state feedback controller includes two parts. The first part, u1(t), whose gains updating automatically between the lower bounds and upper bounds of uncertain parameters, is obtained according to...
In this paper, we study the Belgian Chocolate Stabilization Problem. By using a complex analysis method, following Hempel and Smith's technique, we compute the parameter bound of the stabilization problem ultimately. A more sharper bound for this parameter is obtained.
In this paper, based on the results of complex analysis, we address and analyze some conclusions proposed by V.Blondel et al., which concern the simultaneous stabilization of three linear systems and a special bistabilization problem, named as “Chocolate Problem”. As for the simultaneous stabilization problem of three linear systems, it is shown that there is a slight flaw in the sufficiency part...
A parametric design problem of the finite time state observers for the linear time-invariant systems is investigated. The design aim of the finite time state observers in linear time-invariant systems is to present the parametric form of the state observers which can estimate the system state in a predefined finite time and the estimation stays bounded during the convergence time interval. Based on...
This paper investigates the stability for a class of switched nonlinear systems. Firstly, an improved average dwell time (ADT) method is introduced, based on which an improved mode-dependent dwell time (MDDT) method is established. Then, several new results to the stability analysis are obtained. In comparison with the existing results, the obtained results have some advantages over those obtained...
This paper studies the detectability of discrete-time stochastic linear systems with Markovian jump and multiplicative noises. An equivalent definition of the weak detectability for discrete-time stochastic linear systems will be discussed. And we show that the weak detectability has invariance under the linear output feedback.
This paper investigates the input/output-to-state stable in the mean (IOSSiM) property of switched stochastic nonlinear (SSN) systems. First, we present a new IOSSiM result for the SSN systems whose subsystems are IOSSiM by applying an improved ADT method. Second, by extending the improved ADT method to unforced nominal SSN systems in which parts of subsystems are stable, we establish a new stability...
The issue of H infinite control for multi-rate networked control systems (NCSs) with both time-delay and packet-dropout is discussed in this paper. Compared with traditional NCSs, the sampling periods of the nodes in multi-rate NCSs are different. Based on Markov theory, a new approach is proposed to convert the multi-rate NCSs into a non-uniform sampling system. A stochastic mean-square sate feedback...
In this paper, the problem of finite-time H∞ fuzzy control for both continuous-time and discrete-time nonlinear systems is considered. The definitions and explanations about finite-time H∞ fuzzy control for both continuous-time and discrete-time nonlinear systems are offered. Some theorems are obtained to guarantee the provided performance requirements. The optimization algorithms are also designed...
In this paper, the set invariance condition and disturbance rejection problem of actuator saturation linear systems with disturbance are discussed. Under the control of linear state feedback, the new set invariance condition and new optimal approach to enlarge the invariant ellipsoid are given by using composite quadratic Lyapunov functions method. It is proved that the convex hull of some invariant...
By exploring some geometric properties of the logarithmic quantizer and using the fact that the logarithmic quantizer is sector bounded and nondecreasing, this paper presents a new approach to the stability analysis of quantized feedback control systems. Our method is based on Tsypkin-type Lyapunov functions that have been widely used in absolute stability analysis problems. The results are expressed...
This paper considers stabilization of periodic linear systems with time-varying input delays. The truncated predictor feedback (TPF) approaches established earlier for time-invariant systems are generalized to the time-varying setting. By carefully investigating the solutions and properties to a class of parametric Lyapunov differential equations, it is proved the TPF controllers can indeed stabilize...
This paper investigates the decentralized output-feedback control for a class of large-scale high-order stochastic nonlinear systems with unknown control coefficients. By developing a decentralized high gain homogeneous domination approach, it is shown that under some general conditions, the closed-loop system can be proved to be globally asymptotically stable (GAS) in probability. The efficiency...
In this paper, we investigate the discrete-time antilinear systems with Markovian jumping parameters. The concept of stochastic stability is extended to the context of discrete-time Markovian jump (DTMJ) antilinear systems. By using stochastic Lyapunov approaches, necessary and sufficient conditions are established for a DTMJ antilinear system to be stochastically stable in terms of coupled anti-Lyapunov...
With the wide use of computer and the rapid development of network technology, the research in the emerging area of networked control systems (NCSs) has attracted considerable attention in the research community. The purpose of this survey is to provide a review of state-of-the-art of such research. We particularly discuss things as follows: event-driven sampling for energy and communication efficiency,...
