Adaptive Control for Nonlinear Systems with Time-Varying Control Gain [PDF]
Journal of Control Science and Engineering, 2012 We propose a scheme for nonlinear plants with time-varying control gain and time-varying plant coefficients, on the basis of a plant model consisting of a Brunovsky-type model with polynomials as approximators.

Stochastic Adaptive Control for Exponentially Convergent Time-Varying Systems [PDF]
SIAM Journal on Control and Optimization, 1986 This paper shows that the standard stochastic adaptive control algorithms for time-invariant systems have an inherent robustness property which renders them applicable, without modification, to time-varying systems whose parameters converge exponentially.

Adaptive Control for Systems With Time-Varying Parameters [PDF]
IEEE Transactions on Automatic Control, 2021 This article investigates the adaptive control problem for systems with time-varying parameters using the so-called congelation of variables method. First, two scalar examples to illustrate how to deal with time-varying parameters in the feedback path and in the input path, respectively, are discussed.

Optimal control of (min,+) linear time-varying systems [PDF]
Proceedings 8th International Workshop on Petri Nets and Performance Models (Cat. No.PR00331), 2003 The class of discrete event dynamic systems involving only synchronization phenomena can be seen as linear time-invariant systems in a particular algebraic structure called (min,+) algebra. In the same framework, this paper deals with linear time-varying systems, that is, systems whose parameters may change as functions of time.

Analysis of unconstrained nonlinear MPC schemes with time varying control horizon [PDF]
, 2010 For discrete time nonlinear systems satisfying an exponential or finite time controllability assumption, we present an analytical formula for a suboptimality estimate for model predictive control schemes without stabilizing terminal constraints. Based on

Robust Finite-Time Output Feedback Control for Systems With Unpredictable Time-Varying Disturbances
IEEE Access, 2020 This work presents a robust finite-time output feedback control method for a number of nonlinear systems that suffer unpredictable time-varying disturbances. The developed method takes advantage of control techniques based on a finite-time state observer

Further Results on Strict Lyapunov Functions for Rapidly Time-Varying Nonlinear Systems [PDF]
, 2006 We explicitly construct global strict Lyapunov functions for rapidly time-varying nonlinear control systems. The Lyapunov functions we construct are expressed in terms of oftentimes more readily available Lyapunov functions for the limiting dynamics ...
