中文说明：Park和Clarke的矢量变换是矢量控制的感应电动机的关键之一。 I) 克拉克变换 前向Clarke (1943) 变换并从三个阶段的规模不变翻译 为两个正交分量的系统。如果中性-地面连接被忽视， 变量在三相系统 （A、 B 和 C） 总和等于零，和那里是多余的 信息。
English Description：
The Park and Clarke vector transforms are one of the keys to vector control of induction motors. I) Clarke transform The forward Clarke (1943) transform does a magnitude invariant translation from a three phase system into two orthogonal components. If the neutral - ground connection is neglected, the variables in a three-phase system (A, B, and C) sum is equal to zero, and there is a redundant information.
