提出了天然气内燃发电机组频率采用模糊前馈补偿和模糊pid反馈协调控制的方法，并设计了控制器。
A new frequency control scheme using fuzzy feedforward compensation and fuzzy - PID for natural gas engine generating set was proposed and the controller was designed.

这种控制方法的结构可以被认为是一个前馈型计算转矩控制器和一个WFN模型补偿器的结合。
The structure of this control method can be considered as the combination of a feed forward type computation moment controller and a WFN model compensator.
