Abstract: In this paper, adaptive control of systems using switching techniques is investigated. It is assumed that the plant model belongs to a known finite set of models. It is also assumed that a set of controllers which solve the robust servomechanism problem for the family of plant models and a set of simultaneous stabilizers for certain subsets of plant models are given. It is shown that by using the above set of controllers and simultaneous stabilizers and choosing a proper switching sequence, one can minimize the number of switchings to destabilizing controllers. This can significantly improve the transient response of the system, which is one of the common weak points in most switching control schemes. Simulation results show the effectiveness of the proposed method in improving the transient response.

The Order of Any Stabilizing Regulator is Sufficient a Priori Information for Adaptive Stabilization
Bengt Mårtensson
- 01 Jan 1985
TL;DR: In this article, it is shown that this suffices as a priori information for an adaptive stabilizing controller, which is based on a dense search through parameter space, and does not utilize high gain properties, as opposed to the universal regulators proposed before.

An adaptive tracking problem for a family of retarded time-delay plants
Ahmadreza Momeni,Amir G. Aghdam +1 more
TL;DR: In this article, a multi-model switching control algorithm is proposed for delayed linear time-invariant (LTI) systems, where the system is represented by a family of known multi-input multi-output, observable, LTI models with multiple delays.
Supervisory control of switching control systems
TL;DR: It is shown that in thesupervisory control problem considered in this paper, limitations on event observation are the factors that essentially restrict supervisory control and once observation limitations are respected, constraints on control will be automatically satisfied.

TL;DR: The transient performance which is the main shortcoming of most switching control schemes is improved using the proposed strategy and it is shown that using GSHFs instead of continuous-time controllers reduces the complexity of online computations required to obtain the upperbound signals.

Control System Synthesis : A Factorization Approach
Mathukumalli Vidyasagar
- 01 Jan 1988
TL;DR: In this article, the stable factorization approach is introduced to the synthesis of feedback controllers for linear control systems, where the controller is designed as a matrix over a fraction field associated with a commutative ring with identity, denoted by R, which also has no divisors of zero.

Supervisory control of families of linear set-point controllers - Part I. Exact matching
TL;DR: 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.

Improving transient response of adaptive control systems using multiple models and switching
TL;DR: This paper develops a stable strategy for improving the transient response by using multiple models of the plant to be controlled and switching between them.

Supervisory control of families of linear set-point controllers
A.S. Morse
- 15 Dec 1993
TL;DR: In this paper, a controller called a "supervisor" switches into feedback with a SISO process, a sequence of linear positioning or set-point controllers from a family of /spl Fscr//sub C/ of candidate controllers, so as to cause the output of the process to approach and track a constant reference input.
