基于细菌觅食算法的风力发电机液压变桨距系统的同步控制

摘要

On the basis of the variable pitch control principle of wind generating set, the synchronous control scheme to optimize the control parameters was proposed in the mode of deviation⁃ring coupling with the advantages of bacterial foraging algorithm, in order to study the synchronous performance of multichannel variable pitch system of the independent 2�5 MW wind generating set with differ⁃ent parameters in operation. The results show as compared with using adaptive genetic algorithm, the control scheme has good robust⁃ness and high synchronous accuracy, which can realize non⁃deviation tracking to the input signal.%为研究独立控制的2�5 MW风力发电机组变桨距控制系统在工况中的同步性能，以风力发电机组变桨距控制原理为基础，提出了在偏差－环形耦合控制方式下采用细菌觅食算法对控制参数进行优化的同步控制方案。结果表明：相比采用自适应遗传算法时，该方案具有良好的抗干扰性和同步控制精度，能够实现对输入信号的无偏跟踪。
