compared with traditional voltage vector control ,current vector control gains
main advantages as follow :
1、start torque：0.5Hz,180% rated torque（open loop magnetic flux vector
control ）;
2、Flux-weakening control algorithm, maximum can exceed 2 times the
fundamental frequency operation of motor;
3、precise speed control accuracy: open loop magnetic flux vector control
≤±0.5%（rated sync-speed）,close loop magnetic flux vector control
≤±0.2%（rated sync-speed）；
4、more stable speed control stability: open loop magnetic flux vector control
≤±0.3（rated sync-speed）, close loop magnetic flux vector control≤±0.1%
（rated sync-speed）;
5、faster torque response performance ≤40ms (open loop magnetic flux vector
control)；≤20ms (close loop flux vector control).
