Online continuation method controller for PWM systems

Abstract

A iicw coiitrol algoritliiii for PWM systciiis based on continuation iiietliod lias bccii dcvclopctl. This algoritliiii solves tlic PWM-type deadbeat control problem iiuincrically. By usiiig this algoritliiii. tlic iteration for solviiig tlic iioiiliiicar equation always starts from a good solutioii candidate aiid tlicrcforc it caii be used onliiic. Tlic validity of tlic proposed coiitrol irictliod is dcirioiistratcd by a iiuiiicrical siiriulatioii of cxpcririiciit device imitating a satellite.

Improved Continuation Method Controller for PWM Systems: An Experimental Case Study

“…For this reason, a controller for PWM system not relying on approximation such as linearization nor redesigns is desirable for these applications, and is the primary motivation of our work. We have proposed an online continuation method controller in [6,7], which is a control strategy for PWM systems using numerically calculated solution as the control input. In [7], the regulation problem and servo system problem was considered.…”

“…Only simulations have been done to show the efficiency of our algorithm. Although we have found some merit using our algorithm of [6,7], it is not always recommended to real systems. In this paper, we present an improved version of the continuation method controller which is applicable to real systems.…”
