Torque simulation of wind turbine based on brushless DC motor

In order to solve the problem that the study of wind power generation was restricted by nature conditions, this paper proposed a novel simulation scheme by using brushless DC motor instead of wind turbine, the torque imitation was implemented by controlling the DC side current, and the current loop adopted the control method of radial basis function neural network combined with PI control. A system simulation model was built by Matlab/Simulink, and a hardware platform based on brushless DC motor and permanent magnet generator was also established, which was controlled by DSP. Simulation and experimental results were consistent with theoretical torque, and the torque ripple of brushless DC motor was effectively reduced. This control method is simple with high control precision, and can provide a new idea for the design of the simulation system.
