Abstract :
In this paper, we propose a precise short-span seeking control system based on the pivot friction compensation. The proposed compensator consists of the feed forward compensation with perfect tracking control method and feedback compensation with optimum friction compensation. The effectiveness of the proposed compensator is verified by using numerical simulation.
