MULTI-LAYER SLIDING MODE ROBUST EXCITATION CONTROLLER DESIGN

多重滑模控制对于不满足匹配条件的不确定性具有较好的抑制作用。对于电力系统鲁棒励磁控制模型 ,文中基于多重滑模控制思想设计了励磁控制器。为了获得快速且鲁棒性能较好的动态响应 ,将励磁控制分为鲁棒控制分量和快速响应分量 ,它们分别由多重滑模控制器和 PID控制器产生。基于电力系统分析综合程序 ( PSASP)

Multi-layer sliding mode (MLSM) control may attenuate mismatching uncertainty well. For power system robust excitation control model, this paper designs a excitation controller based oh the idea of MLSM. In order to obtain the performance of fast and robust dynamics response, the excitation input is split into robust control section and fast response section - which are produced by MLSM controller and PID controller respectively. The computer simulation results of small disturbance stability and transient stability based on power system analysis software package (PSASP) verify the validity of the proposed method in power system excitation control.
