Duality parameter of Approximate Dual Control for Electromagnetic Suspension

In dual control, the control input has a dual role so that the system with uncertain parameters should be controlled carefully while obtaining quality system information to identify. This paper deals with the effects of our approximate method of dual control on the performance of electromagnetic suspension system. This method compensates a weakness of model predictive control which requires an accuracy system model. The performance weight between the control and the identification is formulated by a single design parameter. We show simulations when varying the design parameter of magnitude of excitation in order to study the effects on the control and identification result.
