Live-working water washing robot for transformer substation and hydraulic system control method of robot

The invention discloses a live-working water washing robot for a transformer substation and a hydraulic system control method of the robot, and belongs to the field of hydraulic control. The live-working water washing robot for the transformer substation comprises a hydraulic system, wherein a hydraulic pump is connected with a hydraulic motor, a support oil cylinder, an amplitude variation oil cylinder, a telescopic oil cylinder, a pitching oil cylinder and a swing oil cylinder through a hydraulic proportional valve; a sensor feeds back monitored movement information to a movement controller, and the movement controller controls the opening degree of the hydraulic proportional valve through a driving amplifier. According to the live-working water washing robot for the transformer substation and the hydraulic system control method of the robot, not only are the advantages of traditional proportion integration differentiation (PID) control reserved, but also the advantages of a fuzzy control algorithm are added, so that the live-working water washing robot for the transformer substation has self-adapting adjusting capacity under the special working condition of washing in the transformer substation; the control precision and the stability are both greatly improved, the reliability and the anti-jamming capability are enhanced, and the robot has certain robustness.
