摘要
风力发电中的变速恒频风力发电技术是未来风电发展的重要方向,考虑风力发电中的变速恒频风力发电的问题,建立了一种多胞型模型的风力发电机PWM整流器电压环模型.应用凸优化理论中的多胞型模型,采用线性矩阵不等式方法,找到一个状态反馈控制律,使闭环系统的极点配置在一个给定的圆盘中,使得闭环系统的暂态指标满足一定的要求,且闭环系统的传递函数的H∞指标达到最小.算例验证了设计方法的可行性.
A wind turbine generator PWM rectifier voltage loop based on polytypic model was established. By convex optimization theory and the linear matrix inequality approach, the state-feedback law was obtained such that the poles of closed-loop system assigned in a given disk and H infinity indicators of the closed-loop transfer function reaching the minimum simultaneously. The proposed method was verified by numerical example and results show the approach is available.
