High-voltage circuit breaker direct motor driving device and method and state sensing system

The invention relates to a high-voltage circuit breaker direct motor driving device and method and a state sensing system. The high-voltage circuit breaker direct motor driving control device comprises a high-voltage circuit breaker, an operating mechanism, a direct current motor, a main loop, a control loop and a circuit breaker state sensing system. The control method of the device comprises the following steps: designing a position regulator of the servo system of the permanent magnet driving motor operating mechanism into a fuzzy controller capable of adaptively regulating PID parameters, calculating an optimal speed curve as a given value in a DSP chip by collecting voltage and current values of a power grid, and calculating the position of the servo system of the permanent magnet driving motor operating mechanism according to different deviations e and change rates ec of feedback speeds. And performing on-line adaptive adjustment on Kp, Ki and Kd through PID (Proportion Integration Differentiation) to c
