摘　　要：针对永磁同步风力发电机(PMSWG)在最大功率跟踪(MPPT)过程中出现的输入饱和约束问题,提出了一种基于滑模抗饱和控制与端口受控Hamiltonian(PCH)控制的协调控制策略。滑模抗饱和控制解决了PMSWG系统的输入饱和约束问题,并提高了系统的响应速度。PCH控制提高了系统的稳定性和跟踪的准确性。协调控制策略的协调函数是基于双曲正切函数设计的,通过该协调函数可将两种控制方法联系在一起,共同实现对PMSWG系统的控制。仿真结果表明,该协调控制策略既能实现对PMSWG期望转速的跟踪控制,又能解决发电机运行过程中出现的输入饱和问题。In order to solve the problem of input saturation constraint in the maximum power point tracking(MPPT) process of permanent magnet synchronous wind generator(PMSWG), a coordinated control strategy based on sliding mode anti-saturation control and port controlled Hamiltonian(PCH) control is proposed.Sliding mode anti-saturation control solves the input saturation constraint of the PMSWG system and improves the response speed of the system. The PCH control improves the stability of the system and the accuracy of tracking. The coordination function in the coordination control strategy is based on the hyperbolic tangent function, and the two control methods can be linked together by the coordination function to realize the control of PMSWG system together. The simulation results show that the coordinated control strategy can not only achieve the desired PMSWG speed tracking control, but also solve the input saturation problem during the generator operation.
