Abstract

Abstract

En 中文
A model-free approach to linear quadratic (LQ) performance assessment is presented in this paper. First a test for LQ optimality, based on closed-loop signals, is presented. Its result indicates whether the controller should be adjusted. From the same test it is possible to determine the closed-loop pole positions which would be obtained by using the LQ optimal controller. These may then be used in a direct adaptive control scheme to adjust the controller. Both state and output feedback are addressed for discrete-time, single-input-single-output (SISO), linear, time-invariant processes. (C) 1998 Elsevier Science Ltd. All rights reserved.
