Abstract
Coal sampling robot needs to work in the field for a long time. The energy supply of car-borne electrical appliances determines the duration of the coal sampling robot. Driving torque extraction generation satisfies not only the demand of electricity consumption but also the regenerative braking. Because of complicated road conditions and uncertain load, the speed of engine will fluctuate. In order to solve the problem of motor speed fluctuation caused by unstable input speed and load change of hydraulic transmission system, the structure and operation parameters of the system are analyzed in this paper, and measures are obtained to optimize system characteristics. A fuzzy PID control algorithm of compensating the instability of input speed and the change of load is proposed to reduce the fluctuation of output speed of the system.
