Performance optimization of a self-organizing feedback control system in presence of inherent coupling signals

This paper deals with optimization of the response of a self organizing feedback control system in presence of inherent coupling signals. The system contains lenses and phototubes as a sensing element and it always orients its front surface in the direction of the tracked object with the help of light signals received. Adaptive Step Size Random Search (ASSRS) has been used and parameter optimization in presence of different coupling signals was achieved. The results obtained are verified by an inverse sensitivity method. Finally the merits of random search technique are compared with those of the inverse sensitivity method.
