摘　　要：为改善系统输出功率的动态性能和稳态性能,运用一种由带自调整函数的模糊控制器与二元函数的分片双二次Lagrange插值算法相结合的控制算法,并详细分析了该算法实现过程的时效性和控制性能。自调整函数为指数函数,根据控制对象的具体情况和要求,用计算机键盘对自调整函数中的参数进行调试,参数确定后形成以偏差为自变量的自调整函数。为了提高复杂被控系统的控制精度,对模糊控制系统中的量化因子和比例因子进行了在线调整。运用SIMULINK的仿真结果表明,带自调整函数的模糊控制器和Lagrange插值法相结合的控制算法在风力发电机组中的应用显著改善了系统的控制品质和稳态性能。A control algorithm combining the fuzzy controller with self-adjusting function and the slicing binary function Lagrange interpolating algorithm was discussed. The algorithm was proposed to improve the power output quality of the wind turbine. The realization process and control characteristics were discussed and analyzed in detail. The self-adjusting function is an index function. Aecording to concrete situation and requests, the parameters in the self-adjusting function can be adjusted through the keyboard. The burst double Lagrange interpolating algorithm is employed to ensure the time effectiveness of the control system. Quantification factor and scale factor of fuzzy control system is adjusted online to improve control precision of complex system. Simulation results have proved that the control quality and steady-state performance are greatly improved
