A control system that is used for engine main pump angle of aircraft ground testing

The utility model discloses a control system that is used for engine main pump angle of aircraft ground testing. A control system that is used for engine main pump angle of aircraft ground testing includes: the industrial computer, the step motor subassembly, the step motor subassembly with the industrial computer is connected, is used for receiving the signal and the work of industrial computer, throttle handle, throttle handle with step motor's output is connected, just throttle handle's output and engine main pump are connected, throttle handle is used for following step motor subassembly work and moving, and pass through throttle handle's output drives the engine main pump rotates, the angle encoder, the angle encoder is connected with industrial computer and engine main pump respectively for measure engine main pump turned angle, and will the mode of turned angle passing signal transmit for the industrial computer. Adopt this kind of system, can improve and gather precision, high frequency response chara
