The invention relates to the technical field of
engineering machinery, and provides an
aerial work platform and a control method thereof.The
aerial work platform comprises a motor, an electronic pump, a valve set, a
vehicle control unit and a
motor controller, and the
vehicle control unit is used for obtaining a user action instruction and the pressure of a pressure
signal feedback port of the valve set and judging the action type according to the user action instruction; and the
motor controller is used for controlling the displacement of the electronic pump and the rotating speed of the motor according to the output port pressure of the electronic pump, the pressure
signal feedback port pressure of the valve group and the action type. The optimal rotating speed and displacement can be matched for the motor and the pump, control signals are completely based on electronic signals, the environment
interference resistance is high, the main
control mode is integrated in the
motor controller, the response is faster, the composite action and the single action are separated, direct flow control is adopted for the single action, the throttling loss is greatly reduced, and the control efficiency is improved. Load sensitivity and
displacement control are adopted for composite action, and throttling loss can be reduced under some working conditions.
