Appropriate realization of gain-scheduled controllers with application to wind turbine regulation

摘要: Power regulation of horizontal-axis grid-connected up-wind constant-speed pitch-regulated wind turbines presents a demanding control problem with the plant, actuation system and objectives all strongly nonlinear. In this paper, novel nonlinear strategy is devised which, in some sense, optimizes performance across operating envelope. comparison linear control, achieves substantial improvement performance. The realization adopted crucial attaining required An extended local equivalence condition introduced which provides basis for selection an appropriate realization. This important, general, issue design gain-scheduled systems generic realizations, satisfy condition, are derived SISO scheduled upon internal plant or controller variable. For turbine controller, realizations li...
