ADAPTIVE CONTROL FOR AVOIDANCE OR EVASION IN AN UNCERTAIN ENVIRONMENT

For a given class of uncertain dynamical systems we consider the problem of obtaining controllers which assure that the system state avoids a prescribed region. Each controller considered is a combination of a memoryless controller and an adaptive controller. Constructive sufficient conditions are given for the existence of these avoidance controllers. The results are applied to linear systems and pursuit-evasion problems.
