Power Regulation With Predictive Dynamic Quantizer in Power Packet Dispatching System

Abstract

A power regulation algorithm was designed to address the load requirements of a power packet dispatching system of interest. The switch controller, to which the regulation algorithm is applied, was constructed and implemented in the prototype of the power packet dispatching system. This algorithm was designed by extending the optimal dynamic quantizer investigated in the context of control with a discrete-valued signal. In the controller, the prediction of the states for the controlled variable in one packet transmission time before is applied to support the term when the controlled load is insulated from the source. This predictive dynamic quantizer can realize the power regulation for multiple loads simultaneously through a common power line. The stability of the system with the predictive dynamic quantizer is verified analytically as a switched system. The performance of the controlled variable is verified with the series of results from both experiments and numerical simulations. From these results, it was possible to verify that simultaneous voltage demands from multiple loads in the power packet dispatching system are satisfied with the regulation method.
