Funnel control with saturation : nonlinear SISO systems

Tracking - by the system output - of a reference signal (assumed bounded with essentially bounded derivative) is considered in the context of a class of nonlinear, single-input, single-output systems modelled by functional differential equations and subject to input saturation. Prespecified is a parameterized...

Tracking with prescribed transient performance for hysteretic systems

Tracking of reference signals (assumed bounded with essentially bounded derivative) is considered for a class of single-input, single-output, nonlinear systems, described by a functional differential equation with a hysteresis nonlinearity in the input channel. The first control objective is tracking,...

Asymptotic tracking with prescribed transient behaviour for linear systems

The problem of asymptotic tracking of reference signals is considered in the context of m-input, m-output linear systems (A,B,C) with the following structural properties: (i) CB is sign definite (but not necessarily symmetric), (ii) the zero dynamics are exponentially stable. The class of reference signals...

Adaptive and non-adaptive control without identification : a survey

Three related but distinct scenarios for tracking control of uncertain systems are reviewed: asymptotic tracking, approximate tracking with prescribed asymptotic error bound, tracking with prescribed transient behaviour. A variety of system classes are considered, ranging from finite-dimensional linear...

Adaptive tracking for systems described by functional differential equations

An adaptive servomechanism is developed for practical tracking (with prespecified asymptotic accuracy), by the system output, of any admissible reference signal (viz. absolutely continuous and bounded with essentially bounded derivative) in the context of a class of controlled dynamical systems modelled...

Universal λ-[lambda]-tracking for nonlinearly-perturbed systems in the...

For a class l of multivariable, nonlinearly-perturbed, linear, minimum-phase systems of relative degree one, with output measurement noise of Sobolev class W1,00 (absolutely continuous on compact intervals, and bounded with essentially bounded derivative), the following servomechanism problem is solved...

Tracking with prescribed transient behaviour

Universal tracking control is investigated in the context of a class S of M-input, M-output dynamical systems modelled by functional differential equations. The class of systems encompasses a wide variety of nonlinear and infnite-dimensional systems and contains - as a prototype subclass - all finite-dimensional...

On tracking and disturbance rejection by adaptive control

For linear minimum-phase relative-degree-one systems subject to disturbances and nonlinear perturbations, results pertaining to disturbance rejection and adaptive tracking of constant reference signals are presented and discussed in the context of related results in the literature.

Systems of controlled functional differential equations and adaptive tracking

An adaptive servomechanism is developed in the context of the problem of approximate or practical tracking (with prescribed asymptotic accuracy), by the system output, of any admissible reference signal (absolutely continuous and bounded with essentially bounded derivative) for every member of a class...
