The act-and-wait control introduced by Insperger is shown to be related to a form of intermittent control. Theoretical and practical similarities and differences between the two methods are explored.
This paper presents a new stability analysis of linear networked control systems. The new method is inspired by discontinuous Lyapunov functions that were introduced by using impulsive system representation of the sampled-data and of the networked control systems respectively. In the recent paper piecewise-continuous (in time) Lyapunov-Krasovskii functionals have been suggested for the stability analysis...
Predictive model following control mechanical engineering control system can output general signals following the desired ones. In this paper, a method of predictive system will be extended to be a design of linear system with time-delay. The bounded property of the internal states for the control is given and the utility of this control design is guaranteed. Finally, a numerical example is given...
In this paper, consensus problems of continuous-time networked multi-agent systems via sampled control are investigated. The sampled control protocols are induced from continuous-time linear consensus protocol by using periodic sampling technology and zero-order hold circuit. Two cases are considered: 1) networks without sampling delay; 2) networks with sampling delay. For each case, an algebraic-type...
Approximate dynamic inversion (ADI) has been established as a method to control minimum-phase, nonaffine-in-control systems. Previous results have shown that for single-input nonaffine-in-control systems, every ADI controller admits a linear proportional-integral (PI) realization that is largely independent of the nonlinear function that defines the system. This paper extends these previous results...
Based on a method of LMI, a kind of Lyapunov-Krasovskii functional is used, and the controller design is discussed for the linear delta-operator control systems with state delay and input delay, in which the state delay parameter is uncertain. Using a new type of memory feedback controller, the delay-dependent sufficient conditions for the existence of the controller are brought forward in terms of...
So far, the author developed the parametrization of all strictly causal stabilizing controllers in the framework of the factorization approach. The objective of this paper is to extend the previous results, the parametrization of all strictly causal stabilizing controllers with some conditions. Since the factorization approach has been used, the result can be applied to numerous linear system models.
This paper is concerned with simultaneous stability of a collection of continuous-time linear plants whose feedback control loops are closed via a shared digital communication network. Because of the limitation of communication capacity, only a limited number of controller-plant connections can be accommodated at any time instant. Therefore, it is necessary to carefully design the scheduling policy...
This paper addresses the problem of observer-based gain-scheduled Hinfin control for a class of linear parameter-varying systems with time-varying delays in the state. A new delay-dependent and parameter-dependent Hinfin performance criterion is developed with the parameter-dependent Lyapunov approach. Sufficient conditions are presented to design gain-scheduled controllers and state observers to...
