Discrete Control Modeling for Three-Phase SVPWM Rectifier Based on Direct Power Control
摘要
Abstract
To leave out current inner loop and AC voltage sensors used in conventional voltage oriented control to improve dynamic response of control system, the space vector pulse width modulation is integrated with direct power control and on the basis of deriving mathematical model of control system the parameters of outer loop voltage regulator, inner loop power regulator, SVPWM modulation module, system clock, sampling frequency, data bits, coordinate transformation module are designed. The continuous domain model and discrete domain model are set up by Simulink and high-speed digital signal processing platform based on programmable gate array, and the simulation and experimental verification are performed. Results of simulation and experiments show that the proposed method can improve dynamic response of control system and the operation under high power factor can be implemented.关键词
