SELF TUNING ALGORITHM FOR MOTION CONTROL APLICATIONS USING EXTREMUM SEEKING METHOD

This paper deals with automatic tuning algorithm for motion control applications where an electrical actuator is used. In our approach we use a so called extremum seeking algorithm to automatically adjust the controller parameters. The cascade structure of the controller which is commonly used is considered. The tuning algorithm performs a set of experiments with different parameter values and examines the behaviour of the closed loop. The goal is to find a parameter set which minimizes a chosen criterion function with respect to setpoint response and disturbance rejection.
