Abstract :
Often nonlinear feedback controllers are implemented with linear actuators, which have faster dynamics compared with the nonlinear dynamics of the plant and controller models. But how much faster should the dynamics of the linear actuator be to ensure stability of the given nonlinear feedback control system? The paper gives an analysis for the underlying stability issues, and provides quantitative measures for the linear actuators, employed in nonlinear feedback control systems.
