Su, Steven WeidongAnderson, BrianChen, WeidongNguyen, Hung T2015-12-10December 19781424438723http://hdl.handle.net/1885/54973The system multi-realization problem is to find a state-variable realization for a set of systems, sharing as many parameters as possible. A multi-realization can be used to efficiently implement a multi-controller architecture for Multiple Model Adaptive Control (MMAC). We extend the linear multi-realization problem to nonlinear systems. The problem of minimal multi-realization of a set of MIMO systems is introduced and solved for feedback linearizable systems.Keywords: Controller architectures; Feedback linearizable systems; Multiple-model adaptive controls; Realization problems; MIMO systems; Nonlinear systems200910.1109/CDC.2009.53995022016-02-24
