摘要
本文首先基于三相静止坐标系的典型控制方案与基于d-q同步旋转坐标系的矢量控制方案作了比较,然后运用功率平衡的原理对本文给出的矢量控制方案进行了系统设计,并在此基础上提出一种前馈控制策略并进行了仿真验证。
A new vector control scheme with feed forward compensation strategy is presented.The averaged small signal technique is used to get the control-to-output transfer function.The closed controllers,including the voltage loop and the current loop,are designed.The conclusion that the new scheme can improve the steady-state and dynamic response is verified by simulations.This thesis constructs a steady-state mathematical model of three-phase high power factor ac-to-dc voltage source converter by the power-balance equation and the phasor graph.It studies the relationship between the system parameters and power factor.The equivalent resistors of the input inductors being taken into account,the relationship is more valuable in theory and in practice than that deduced by the literatures which omitting the resistors.The equations are verified by simulations.
