| 摘 要： | 额定风速以下时,风能转换系统需要通过控制发电机转速使风能的捕获率最大.根据风速的多时间尺度特性,建立风能转换系统的非线性机理模型并得到其归一化误差的线性参数变化系统模型;在采用PI控制策略的基础上,设计了基于LPV模型的增益调度控制器,对风能转换系统的电磁转矩进行动态补偿.基于dSPACE的风能转换系统硬件在回路仿真平台进行实验分析,结果表明补偿后系统的功率系数和叶尖速比追踪其最优值的精度更高,鲁棒性更好,体现了更好的动态性能.

| Abstract: | When the wind speed is below the rated value,the generator is controlled to maximize the captured wind energy.According to multi-time scale of wind speed,the nonlinear mechanical model for wind energy conversion system(WECS) is established.And then the Linear Parameter Varying(LPV) system model is developed.Based on PI control strategy,the LPV gain scheduling control is taken as dynamic compensation technology for the electromagnetic torque.The experiment results based on hardware-in-the-loop simulation pla... |
