摘　　要：应用多变量非线性控制的逆系统方法,将双馈风力发电机这一多变量、非线性、强耦合系统精确解耦成有功和无功两个一阶线性子系统。对形成的伪线性系统,引入一种改进型内模控制结构,提高了控制系统的鲁棒稳定性和高阶无静差跟踪性能。仿真结果表明,提出的基于逆系统内模控制策略成功实现了有功、无功的解耦控制和最大风能追踪控制,系统具有更高的控制精度和稳定性。Applying the inverse system method of muhivariable nonlinear control, the doubly-fed wind power generator precisely is decoupled into two first-order linear subsystems of active and reactive power which is a muhivariable, nonlin- ear and strong coupling system. Introduce a modified internal model control structure to the pseudo linear system, to im- prove the robust stability and high order no static error tracking performance of the control system. Simulation results show that the proposed internal model control strategy based on inverse system, has successfully realized the decoupling control of active and reactive power and the maximum wind power tracking control, the system has higher control preci- sion and stability.
