求。其仿真算法对于实现数字化控制变频调速系统具有一定的价值。
(To provide the necessary design parameters for the actual motor control system, the modeling course of
voltage space vector pulse wide modulation（SVPWM）agrithmetic and AC motor under Matlab/Simulink environment
are introduced. The dynamic model of variable frequency speed regulating system based on vector control is
discussed according to the principle of SVPWM. The new method of realizing simulation, key problems and
results of the simulation are analyzed in detail. The experimental simulation results show that this system has
smaller fluctuations of voltage and torque, quicker response speed, and all of the indicators accord with the
performance of the actual motor. The simulation agrithmetic have value to realize controlling motor with digital
signal processing.

关于TCR+FC型SVC的研究文献，这篇文章考查了晶闸管控制的并联补偿器的理论基础。不平衡负荷补偿和电压稳定的条件是建立在对称分量的应用上的。适用于前馈控制（电脑的）的数学关系是根据。这里对前馈和反馈的实用方法进行了讨论。(This paper examines the theoretical foundations of thyristorcontrolled shunt compensation. Conditions for unbalanced load compensation and voltage stabilization are established with the use of symmetrical components. Mathematical relationships applicable to feedforward (computational) type controls are derived. Practical approaches to both feedforward and feedback type controls are discussed.)
