Research of Intelligent Control Strategy for Variable Frequency Pump Based on Wind Power Generation

Aiming at characteristics of wind driven generator and inverter，a model structure of wind power variable frequency pump was proposed，which was a coupling system of two input and two output.Maximum power tracking of wind power generation would be achieved by disturbing output frequency of Alternating Current（AC）of inverter，while holding input voltage of inverter be constant.Based on the principle of decoupling and recurrent neural network，two Diagonal Recurrent Neural Network（DRNN）was adopted to adjust the parameters of two PID controllers on-time，and one nerve cell decouple compensator was adopted for decoupling the system，which implementing non-model adaptive decouple PID control.Finally，validity of proposed control strategy was revealed via computer simulations，and it would be foundation for more study.
