摘要
该文基于微分几何理论,从状态空间的角度出发对双馈异步风机(doubly fed induction generator,DFIG)的机侧变换器和网侧变换器独立设计,通过构造微分同胚变换将其动态模型精确线性化并设计相应的非线性控制律,实现了多目标最优控制.通过仿真验证表明,基于状态反馈精确线性化的双馈异步风机最优控制策略能有效抵御外界风况和电网电压的剧烈变动并快速恢复稳定,呈现优良的抗扰特性.
Abstract
Based on the differential geometry theory,the optimal control strategy of rotor side converter and grid side converter of doubly fed induction generator(DFIG)are designed independently from the perspective of state space.By applying diffeomorphism transformation,the dynamic model of DFIG is linearized exactly.The corresponding nonlinear control law is designed,realizing multi-objective optimal control.The simulation results show that the optimal control of DFIG based on feedback linearization can effectively resist the drastic changes of wind conditions and grid voltage,demonstrating excellent anti-disturbance characteristics.
