自适应PID控制在风力发电机试验系统的应用

将模糊自适应的控制模型与常规PID控制算法相结合,设计一种自适应模糊PID控制器,利用这种控制器的控制参数在线调整功能,以适应被控过程的参数时变性,并将其应用于风力发电机试验系统电源组的控制系统,来改善试验系统电源组的控制性能.结果表明,控制器参数易于整定,且具有较好的自适应性.应用自适应模糊PID控制的风力发电机试验系统电源组的控制系统能够适应被控对象在较大范围内的变化,具有较强的自适应性和优良的控制性能.

Adaptive PID Control in Wind Generator Test System

Combining the model of fuzzy adaptive control with the conventional PID control algorithm, an adaptive fuzzy PID controller is designed. The control parameters are adjusted according to online features of this controller, to adapt to the time-varying of the controlled process parameters, to apply to the wind power generator test system power group, and to improve the control performance test system of power group. The results show that the parameters of the controller are easy to tune, and have good adaptive abil- ity. The control system of the power supply group wind generator test system with fuzzy adaptive PID con- troller is adaptable to the large change of controlled objects and satisfactory adaptive ability. It has a strong adaptability and excellent control performance.
