摘要
以微分几何理论为基础,结合灰色预测理论、非线性控制系统理论和变结构控制理论,为静止无功补偿器(SVC)设计一种新型非线性灰色滑模控制器。灰色预测理论的引入有效地减弱滑模控制系统存在的“抖动”,以改善系统的稳定性。仿真结果表明,在具有NGSMC控制的SVC作用下,电力系统的功角和接入点电压更稳定。
The grey prediction is integrated into the SMC to develop a nonlinear grey sliding mode controller （NGSMC） for static var compensator （SVC） on the basis of differential geometry. The chatting which exists in sliding mode control system can be reduced by leading grey prediction into sliding mode control system. Simulation results show that SVC with NGSMC improve power angle stability of power system and local voltage characteristics of SVC.
