An intelligent control and decision-making (ICD) approach that integra
tes expert systems technology with adaptive algorithms is presented. T
he controller parameters of adaptive systems can be determined using h
uman expertise and knowledge, and they can also be adjusted based on a
ctive monitoring and identification. Decision-making, fine tuning and
inexact reasoning provide the end-user and the control engineers with
a natural and integrated methodology for use with intelligent control
systems. Computer simulation results demonstrate the utility of the pr
oposed technique that is an effective intelligent control and decision
approach. The ICD system is implemented using a Lisp based expert sys
tem shell on an IBM PC.
