基于转矩观测的非线性最大风能追踪控制
Nonlinear Maximal Wind Energy Tracing Control Based on Torque Observation
摘要
Abstract
For the nonlinear characteristic of wind power system,a I2 norm optimal robust speed controller based on dissipative system theory framework was designed,which effectively improve system robustness and response.However,the practical application of this algorithm is greatly restrained by changing aerodynamic torque.Therefore,a torque observer was designed to overcome bad effect of aerodynamic torque variation.To ensure the accuracy of torque observer,the rotational inertia that have been identified online is used to update the parameters of the observer,which can greatly improve ability to resistance disturbances of the system.Being 1.5 MW direct-driven permanent-magnet wind turbine as an research object,the results of simulation and experiment show that this control strategy can achieve rapid wind speed tracing,and had strong robustness for unknown disturbances of wind speed fluctuation.关键词
