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

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.

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.

Topological equivalence of linear time-varying control systems
IMA Journal of Mathematical Control and Information, 2023Abstract In this paper, we mainly studied the topological equivalence of linear time-varying (LTV) control system $\dot{x}\left ( t\right )=A(t)x(t)+B(t)u(t)$ defined on an interval $I \subset \mathbb{R}^{+}$. After giving a new definition of the topological equivalence, we investigated the local equivalence of LTV control systems under ...

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).

Controllability and observability of linear time varying singular systems
IEEE Transactions on Automatic Control, 1999Summary: Controllability and observability of analytically solvable linear time-varying singular systems are considered. Our analysis includes the possible impulsive zero-input response. Based on the definitions of controllability and observability naturally extended from the ones adopted in the time-invariant setting, sufficient and necessary ...
