Instrument drive control system and method

The invention discloses an instrument driving control system and method. The system comprises a main controller and at least two degree-of-freedom driving modules, each degree-of-freedom driving module comprises a driver, a first encoder, a target motor, a speed reducer and a second encoder, first motion information corresponding to the target motor is detected through the first encoder, and current motion information of the target motor is converted through the speed reducer; and detecting second motion information corresponding to the target motor output by the speed reducer through a second encoder, sending the second motion information to drivers of other degree-of-freedom driving modules, obtaining first motion information and second motion information of the target motor from the drivers through the main controller, and sending the first motion information and the second motion information to the target motor. And whether the freedom degree driving module where the target motor is located has a fault is
