Simultaneous Interconnection and Damping Assignment Passivity—Based Control: Two Practical Examples

摘要

We have presented an extension of the highly successful IDA-PBC methodology, called SIDA-PBC, where the energy-shaping and damping injection tasks are not performed sequentially, but simultaneously. In this way we enlarge the class of systems that can be stabilized using PBC and, furthermore, through the consideration of a broader set of desired damping matrices, we provide the designer with more tuning knobs to improve performance.rnThis new idea has been applied to solve the long standing problem of IDA-PBC of induction motors, that turns out to be unsolvable with a two stage design. Also, by avoiding the classical nested-loop control configuration prevalent in electromechanical systems, we have been able to improve the mechanical response of a DFIM, working both as a motor and a generator. Experimental validation of the two control algorithms is currently being terminated and will be reported in the near future.
