The Application of BP Algorithm in Electronic Load Current Control

Abstract:

The current control method based on double hysteresis current control and space vector is taken, so that the current tracing control of three phase VSR can realized. The predictive current control based on BP algorithm is presented, and the drawback that there is beat during the control of SVPWM based on hysteresis can be made up, which has serious influence on the current tracing when the difference value changed violently. Without the rise of sampling frequency, the reference offset current of next time is predicted using of historical current. The simulation results show that the predictive current control based on BP algorithm is correct and valid. The deadbeat control of SVPWM based on hysteresis is realized, less harmonic current and better tracing are got.
