一种采用虚拟磁链模型预测的新型PWM算法
A Novel Algorithm of PWM Using Virtual Flux Model Prediction
摘要
Abstract
In allusion to pulse-width modulation (PWM), a novel algorithm of pulse width modulation (NPWM) was proposed based on virtual flux model prediction. The virtual flux models consisting of sinusoidal modulation voltage and converter output voltage were established. The cost function was built aiming at making the flux error minimum. And the optimal objective voltage vector was obtained by using model prediction. On the basis of single target predictive method, a type of multi-target predictive method was put forward whi’ch ensures that the device’s average switching frequency was reduced under the premise of certain range of flux errors . The algorithm flow was analyzed according to the established cost function. The control effect of NPWM and space vector pulse width modulation was compared by simulations and experiments, which verifies the effectiveness of NPWM in the two predictive methods.关键词
