摘要:

This paper presents a stabilization scheme for a class of multi-input/multi-output systems with nonlinear additive perturbations using high-gain adaptive controllers. The nominal system is assumed to satisfy some mild conditions required by standard adaptive control schemes, and the perturbations certain structural conditions. The controller is a dynamic output feedback containing a gain parameter, which is adjusted with a simple adaptation rule. The result is also applied to decentralized stabilization of a class of interconnected systems, where the interconnections are treated as perturbations to nominally decoupled subsystems.

摘要:

Using the transfer approach, we give, under internal stability conditions, a necessary and sufficient condition of equivalence between open-loop precom-pensation and a closed-loop configuration that consists of dynamic output feedback and inside-loop precompensation. Our result is the generalization of Hammer's result (Hammer 1983) to the general case. This result emphases the use of skew-prime relationships. The parametrization of this problem's solutions will throw new light on multipurpose controllers.

摘要:

In this paper we examine the problem of internally stabilizing, and simultaneously diagonally decoupling, a linear multivariable system by two-parameter compensation. Based on our earlier results (Boussaïd and Guérin 1996) we prove that any given plant (P) of full row rank can be decoupled with stability by the considered configuration. Computation of the decoupling compensators follows by easy constructions. The decoupling problem with a minimum number of unstable zeros in the decoupled system is also formulated and solved in the ‘generic‘ case.
