Abstract :
An extremum controller based on a pulse technique is examined. Plants consisting of the cascade of a piecewise linear static function and a LTI system are considered. Numerical methods for stability and performance analysis of the closed-loop systems are derived. Performance is measured by the ability to track a time-varying optimal point. An illustrative example where it is desirable to control the process to a saturation instead of an extremum is finally presented.
