Application and research on deadbeat control for active power filter
摘要
Abstract
Active power filter is a common equipment for harmonic control. PWM convertor control is the key part of active power filter. Among numerous of control methods, space vector pulse width modulation(SVPWM)is widely used due to its high voltage utilization and good control precision, but time delay is inevitable because of the large amount of computation. The time delay can be eliminated effectively by deadbeat control, but the premise is that the next moment command current should be pre⁃dicted accurately. To reduce calculation quantity and improve prediction accuracy, a new and simple current prediction method is proposed. The new method was simulated by Matlab simulation software, and the hardware experiment was implemented by hardware platform. The simulation results and experiment results verified that the new method is feasible.关键词
