Abstract

This paper deals with the regulation and stabilization of lightly damped systems under plant uncertainty. A controller consisting of a neural-network-based mode separator together with a modular passband tuning regulator is proposed. The mode separator generates the in-phase components of the plant utilized by the passband tuning regulator to maintain closed-loop stability and asymptotic regulation. This combined controller is robust and requires minimal plant information to operate. A synthesis procedure is outlined in this paper to summarize the design steps in a systematic manner. Finally, the application of the passband controller to the stabilization of a magnetic leadscrew is considered. Resonance is shown to be completely eliminated. The stabilization time of the transient response is also significantly reduced, confirming the feasibility of the controller. © 2008 IEEE.
