Automatic resonant cancellation using genetic search

Automation is the future trend for the target tracking systems of the Smart Munitions Test Suite (SMTS) at White Sands Missile Range (WSMR), Resonances often appear in electro-mechanical systems and tend to reduce the performance of the control tracking algorithms, Hence, automatic resonant cancellation is one of the algorithms that should be considered. Tn this paper the concept and implementation of automatic resonant cancellation using Genetic Algorithms (GAs) in conjunction with the system identification package and the notch filter developed by the DSP Control Group is presented A simple GA is used to search for the highest resonant peaks caused by imperfect coupling between motor and load. The search is guided try a fitness function which is the transfer function obtained from a system identification method.
