摘要
针对扰动法固定步长所导致的振荡大或跟踪时间长的问题,提出了基于曲线比较的扰动法,它在P-V特性曲线的基础上,构建了一条过原点的直线,在直线的辅助下,加快了跟踪速度,并提高了效率.通过Matlab/simulink搭建了模型,进行了仿真,仿真结果证明了该方法的有效性.
In view of the problem of disturbance and observation method caused by large size of a fixed step or a long time of tracking,a perturbation method is proposed based on curves comparison of the perturbation and observation method.On the basis of the P-V curve,a straight line through the origin is constructed and with the aid of the line the tracking speed increases and the efficiency is enhanced.A model of the simulation is built via Matlab/simulink and the simulation results verifies the effectiveness of the method.
