Abstract :
The study of desired loop shape and design of on-track mode controller are discussed. The desired loop shape is expressed as the performance shaping function. The controller is designed using loop-shaping technique to maintain stability margins. Simulation and experimental results validate the effectiveness of the proposed controller
