Control of nonlinear time-varying systems
1981 20th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes, 1981Consider the time-varying nonlinear system of the form x(t) = f(x,t) + ?i=1 mui(t)gi(x,t), with f, g1,...,gm being l? vector fields on Rn+1. We give necessary and sufficient conditions for this system to be transformable to a time-invariant controllable linear system.

On the controllability of systems with a time-varying delay†
International Journal of Control, 1971This paper is concerned with the controllability of a system with a time-varying delay. The system to be considered here is described by a linear differential-difference equation of a retarded type, where a time-varying delay is a certain class of a time-varying function. First, the concepts of controllability for linear differential-difference systems

Adaptive Control of Time-Varying and Nonlinear Systems
1994This chapter contains theoretical concepts that are more advanced than those used in the preceding chapters. These concepts and several references are used to show that the preceding adaptive controllers still maintain stability with respect to boundedness even for certain classes of time-varying and nonlinear systems.

Controllability and observability for time‐varying switched impulsive controlled systems
International Journal of Robust and Nonlinear Control, 2010AbstractThis paper is concerned with the controllability and observability for linear time‐varying switched impulsive systems. First, some new results about the variation of parameters for time‐varying switched impulsive systems are derived.

H/sup ∞/ control for linear time-varying systems: controller parameterization
IEEE Transactions on Automatic Control, 1999The \(H^\infty\) control problem is studied for finite-dimensional linear time-varying (FDLTV) systems of the form: \[ \begin{aligned} \dot x(t) & =A(t)x(t)+ B_1(t)w(t)+ B_2(t)u(t)\\ z(t) & =C_1(t)x(t)+ D_{12}(t)u(t)\\ y(t) & =C_2(t)x(t)+ D_{21} (t)w(t)\\ x(0) & =0,\;t\in \mathbb{R}^+ \end{aligned} \] where \(x\in \mathbb{R}^n\) represents the state, \(

Various approaches to control of systems with time-varying delay
International Journal of Modelling, Identification and Control, 2011The paper is focused on control of single-input single-output (SISO) systems with harmonically time-varying delay. Three different approaches to continuous-time control are presented and compared. The first technique uses a modified PI-PD Smith predictor in combination with standard forms for minimum of integral squared time error (ISTE).

ADAPTIVE CONTROL OF A CLASS OF LINEAR TIME VARYING SYSTEMS
IFAC Proceedings Volumes, 1983The key contribution of the paper is to develop a new and explicit characterisation of the concept of persistency of excitation for time invariant systems in the presence of possibly unbounded signals. The implication of this result in the adaptive control of a class of linear time varying systems is also investigated.
