摘　　要：传统的双馈风力发电机(doubly fed wind power generator,DFIG)采用定子定向磁链控制技术,没有考虑到风速波动性、风机非线性以及满足控制鲁棒性等特点。在此基础上提出了基于哈密尔顿函数的DFIG-ESS(energy storage system)协调控制策略,推导了李亚普洛夫意义下的控制器的参数稳定域,证明了控制器满足稳定性的条件。设计和构建了基于MSP430单片机的DFIG-ESS的控制试验系统,在随机风条件下进行控制效果试验,取得了良好的控制效果,为双馈风力发电机的非线性鲁棒控制器的硬件平台设计奠定了基础。The traditional control technology of doubly fed induction generator （DFIG） is based on stator flux-oriented control technology, but not considering wind speed fluctuation, the non-linear and robust control of wind generator. So a coordination control technology of DFIG-ESS （ energy storage system） was proposed based on Hamilton function, to deduce the Lyapunov＇s stability region of controller parameters, and to prove the stability condition of controller. Then, the control test system of DFIG-ESS was designed and built based on MSP430 MCU, which has achieved good results through experiments under random wind. The research results have established the foundation for the hardware platform design of nonlinear and robust control system of DFIG.
