The control system comprises a hydraulic station, a servo oil cylinder and an integrated multi-path oil block, the hydraulic station is provided with a T connector and a P connector, the P connector is connected with a P1 connector of the integrated multi-path oil block through a pipeline, the P1 connector is divided into two paths at the same time, and the P connector is connected with a P connector of the integrated multi-path oil block through a pipeline. Wherein one path of the connector P1 is connected with an outlet of the superposition pressure reducing valve, the other path of the connector P1 is connected with a port P of the two-position four-way direction valve, a port A of the two-position four-way direction valve is connected to a port A2 of the integrated multi-way oil block, and meanwhile a port B of the two-position four-way direction valve is connected to a port B2 of the integrated multi-way oil block; external control type one-way valves for preventing leakage are arranged at the port A and
