This paper describes a discrete-time "high-level" controller, called a "supervisor", capable of switching into feedback with a discrete-time single-input/single-output (SISO) system, a sequence of linear two-degrees-of-freedom (2-DOF) set-point controllers. Each controller is selected among a family of candidates so as to cause the output of the system to approach and track a constant reference input. It is shown that the proposed supervisor can stabilize the loop and ensure a zero set-point…

A Bound for the Disturbance - to - Tracking - Error Gain of a Supervised Set-Point Control System

1 The aim of this paper is to provide a simple analysis of the dynamical behavior of a set-point control system consisting of a poorly modelled process, an integrator and a multi-controller

Hierarchically supervised control of linear plants with unpredictable mode-switch dynamics

A mode-switch process is defined allowing a linear, piecewise time-invariant plant to switch, from time to time, from the actual configuration to another one of a given family of linear,


Abstract This paper presents a new supervisory control scheme, which is based on a control-relevant switching logic. Unlike most of the existing switching methods considering only estimator

A simple analysis is given of the behavior of a set-point control system consisting of a poorly modelled process, an integrator and a multi-controller supervised by an estimator-based algorithm

Switching Control of Stochastic Linear Systems: Stability and Performance Results

In presence of large uncertainty, traditional methodologies based on a single controller do not provide, in general, satisfactory performance when applied to any system in the uncertainty set, and

It is shown that in the absence of unmodeled process dynamics, the proposed supervisor can successfully perform its function even if process disturbances are present, provided they are bounded and constant.

In this paper, we develop a method for adaptive stabilization without a minimum phase assumption and without knowledge of the sign of the high frequency gain. In contrast to recent work by Martensson

Adaptive Robust Control: A New Approach

In this paper we present a new approach to adaptive robust control. The essential idea involved is to fragment modeling uncertainty in a physical plant into "small" families of plant models for which
