Transient control strategy of doubly-fed fan based on zero dynamic and super twist control
摘 要:为充分考虑双馈感应发电机(doubly-fed induction generator, DFIG)故障状况下的非线性特性, 使用一种参数自适应超扭曲滑模控制器(super-twisting adaptive sliding mode control, STASMC)对多输入多输 出(multiple input multiple output, MIMO)系统的零动态(zero dynamics, ZD)方法进行改进,提出一种 ZDSTASMC控制方法用来提高DFIG的暂态电压稳定性.使用ZD方法解耦了原始系统的内部和外部动态,简 化控制设计任务.为进一步提高在参数不确定性和外部扰动下的电压调节能力,将ZD方法与STASMC相结 合,通过STASMC构造辅助输入提升了DFIG的暂态性能,减少建模误差和实际过程中各种误差的影响.改 进后的ZD方法可减小线性化误差的影响,加强了DFIG的暂态性能.通过算例在三相故障下的仿真,验证 了所提ZD-STASMC控制相比ZD控制方法以及常规比例-积分控制方法,在故障期间有更好的暂态性能,故 障切除后也能更快恢复稳定.ZD-STASMC策略能有效增强DFIG的故障穿越能力.
