Adaptive control for a class of time-varying nonlinear systems

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
In this paper we present a direct adaptive control method for a class of time-varying nonlinear systems with unknown nonlinearities. We view the time-varying systems as composed of a finite number of "pieces," which are interpolated by functions that depend on a possibly exogenous scheduling variable.

Relative controllability of nonlinear systems with time varying delays in control

Kybernetika, 1985
Using the measure of noncompactness of a set and Darbo's fixed point theorem, sufficient conditions for relative controllability of nonlinear systems with time varying lumped multiple delays in control are established. This method is extended to perturbed nonlinear systems and to systems having implicit derivative.

Optimal control of time-varying fault tolerant systems

2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004
In this paper an optimal control law for continuous infinite time-varying stochastic control systems with jumps and quadratic cost is found under assumption that the coefficients have limits as time tends to infinity and the boundary system is absolutely observable and stabilizable.

Control and Identification of Time Varying Systems.

1984
Abstract : Research is summarized for the state feedback stabilization of point-delay and distributed-delay time-lag control systems via the development of a reducing transformation technique. The approach facilitates the controller design using well established delay-free methods once the unstable pole set is delineated for the time-lag system ...

A constant-rank theorem for time-varying control systems

52nd IEEE Conference on Decision and Control, 2013
In this paper, we partially extend a constant-rank theorem of S. A. Vakhrameev to time-varying control systems. This theorem completely characterizes constant-rank control systems in terms of invariant subspaces. The extension is partial, in the sense that it only applies to control systems evolving on a Euclidean space.

On the constrained controllability of linear time-varying discrete systems

IEEE Transactions on Automatic Control, 1999
In this paper, the authors study the constrained complete controllability to the origin of various classes of time-varying discrete-time systems under an assumption of a Kalman-type uniform controllability. They will give sufficient conditions for complete controllability for both stable and unstable systems.
