摘要:
为了实现风能转换系统在额定风速以上的恒功率控制,必须同时控制桨距角和电磁转矩。针对变速变桨风能转换系统具有强非线性和不确定性难于建立精确模型的问题,将数据驱动的最优控制理论和多变量控制策略相结合,根据变速变桨风能转换系统的输入输出数据得出系统的马尔可夫参数,据此构造一个基于数据的状态观测控制器,并通过差分Riccati方程的闭合解来设计多变量最优反馈控制器。在MATLAB/Simulink的仿真结果表明:在不建立模型的基础上设计的数据驱动的多变量最优控制器能够有效地实现系统的恒功率输出控制。
Abstract:
To achieve the constant power control of the above rated wind speed,pitch angle and electromagnetic torque of the wind energy conversion system(WECS)must be controlled simultaneously.The nonlinearity and uncertainty of the variable speed variable pitch wind energy conversion system results in the difficulties in modeling.Combining the data-driven optimal control theory with multivariable control strategy,according to the input and output data of the variable speed variable pitch wind energy conversion system to calculate the Markov parameters.A data-driven state observer controller is constructed.A multivariable optimal feedback controller is designed by the closed form of difference Riccati equation.Simulation in MATLAB/simulink results indicate that the above rated wind,the data-driven multivariable optimal control without modelling can effectively maintain the rated power output.
