Bayesian adaptive control of time varying systems

[1992] Proceedings of the 31st IEEE Conference on Decision and Control, 2005
Linear stochastic systems corrupted by Gaussian white noise disturbances are considered. An elementary proof of boundedness of the mean square response under a certainty equivalence minimum variance control law is described. The assumptions used in this ideal case indicate that the usual smallness in the mean conditions used in adaptive control could ...

Adaptive Control of Fast Time-Varying Systems

IFAC Proceedings Volumes, 1992
Abstract In this paper, the state of the art and a perspective about adaptive control of fast time-varying systems are given. The emphasis is on the prediction of fast time-varying parameters. It is shown that the techniques for tracking and predicting fast time-varying parameters are based on the knowledge about variation in the parameters.

Controllability of time‐varying fractional dynamical systems with prescribed control

Mathematical Methods in the Applied Sciences
The study of this article deals with the controllability results for time‐varying fractional dynamical systems in terms of Caputo‐type fractional derivatives having a prescribed or predetermined control. We demonstrate the controllability results for time‐varying linear fractional dynamical systems using Gramian technique and fractional calculus ...

Robust nonlinear control of time-varying systems

Proceedings of 1995 American Control Conference - ACC'95, 2005
For a class of SISO nonlinear time-varying systems, we present a robust output feedback control scheme. The control scheme removes some of the structural constraints so as to enlarge the class of systems that can be handled by recently developed nonlinear control schemes. The enlargement can be seen via four aspects: 1) all the unknown coefficients and

Repetitive Control for Linear Time Varying Systems

Dynamic Systems and Control, 2002
Repetitive control that asymptotically tracks or rejects periodic signals has been widely used in many applications. For linear time invariant system, this problem has been thoroughly studied and solved. This paper presents the analysis and synthesis of repetitive control algorithms to track or reject periodic signals for linear time varying systems ...

Nonstationary robust control for time-varying system

Proceedings of the 2004 American Control Conference, 2004
This work presents a synthesis method of nonstationary robust controller for a time-varying system considering various uncertainties. For the uncertainties, a scaled structured uncertainty is regarded as weightings for variations of parameters and a design function in the time domain.

Adaptive Control of Time Varying Stochastic Systems

IFAC Proceedings Volumes, 1990
In many practical applications, the system structure is often unknown or just partially known; not only may it suffer from random disturbances but also its parameters may vary with time. The drifting or jumping phenomena of parameters in a system is one of the motivations for adaptive control since classical design methods may be difficult to use for ...

Adaptive control of simple time-varying systems

Proceedings of the 28th IEEE Conference on Decision and Control, 2003
The adaptive control of simple linear time-varying systems is treated for the case in which their parameters vary arbitrarily in an unknown compact set. The state variables of these systems are assumed to be available for measurement. It is shown that all the signals in the adaptive system are bounded for any bounded reference input.

Adaptive Control for Time-varying Nonlinear System

2009 International Conference on Computer and Automation Engineering, 2009
An adaptive control scheme is proposed for a kind of time-varying nonlinear systems. In the scheme the nonlinear systems are divided into a finite number of subsystems, which are in strict feedback and interpolated by functions of an exogenous scheduling variable. The adaptive method yields stability of all signals in the closed-loop.

Adaptive control of linear time varying systems

Proceedings of 35th IEEE Conference on Decision and Control, 2002
A new class of adaptive controllers for linear time varying systems is designed and analyzed using nonlinear design techniques and the certainty-equivalence approach. It is established that this new class of controllers guarantees robustness with respect to unknown but slow parameter variations in the global sense.
