Abstract

In this paper, according to the structural characteristics of two-leaf semi-rotary VAWT(vertical axis wind turbine), the micro- element method and the coordinate system rotation method are used to establish the mathematical model of wind turbine and, the mathematical model is simulated in the MATLAB platform by using the PID control method based RBF neural network tuning. The simulation result shows the revolution speed of VAWT can converge to rated value in a relative short period time after wind speed increasing.
