Estimation of Scheduling Parameters by Disturbance Observer

This paper proposes a method for estimating scheduling parameters using a disturbance observer. The input and output values of the scheduling parameters are estimated by a disturbance observer, and the scheduling parameters are estimated by calculating the ratio of these values. The effectiveness of the gain-scheduled control using the estimated values is verified by comparing the gain-scheduled control with actual scheduling parameters and the conventional robust control designed by the scaled $H_{\infty}$ control.
