A Time Delay-Based Gain Scheduled Control for Electromagnetic Suspension System
This paper proposes a robust gain scheduled control technique using time-delay for the nonlinear systems with model uncertainty and unexpected disturbances. The time-delay-based gain scheduling method depends on a direct estimation of a function representing the effect of uncertainty. The information from the estimation is used to cancel the unexpected disturbances simultaneously. The time-delay-based gain scheduled control uses the past observation of the system's response and the control input to directly modify the control actions rather than to adjust the controller gains or to identify system parameters. The benefits of this proposed scheme are demonstrated in the simulation of an electromagnetic suspension system with model uncertainty and external disturbances, and the method is compared with the conventional state feedback controller.
