Abstract :
This article presents a methodology for LPV (Linear Parameter-Varying) control system design. A weighted sum of robust LTI (Linear Time-invariant) controllers is employed, where the weights are adapted on the base of an estimation of the radius of the reel. Robust stability of the loop is guaranteed. Performance of the LPV control system is analyzed and compared with a LTI H∞ controller and a PID controller. Experimental results show that the LPV controller offers better performance in terms of stationary state error and rejection of disturbances.
