Abstract :
According to the characteristics of wind field control system such as delay and uncertainty, hydrodynamics theory and modern control theory are used to design and achieve a practical wind field control system. Firstly, the mathematical model of the wind speed distribution of the system is analyzed from the angle of hydrodynamics. Then the Galerkin method is used to turn it into state space expression in lumped parameter form. Finally, through the estimation of the system state and optimal control, the wind field uniformity control is implemented. The simulation results show that this algorithm has good robustness and anti-interference ability.
