In order to compensate for the influence of temperature, control voltage, ageing and other disturbances, guarantee that the operating times will remain stable in the long term, a high accurate position control of synchronous VCB is presented. An adaptive fuzzy controller of controlled motion was developed to ensure the movable contact of the circuit breaker always follows the pre-defined optimal travel curves. Test the vacuum circuit breaker´s operating characteristics, the test results show that the position control can meet with the consistency of operating times requirements of IEC62271-302 for synchronous switching and the drifts of operating times are less than ± 0.5ms.
