The invention discloses an electric-hydraulic proportional integrated controller and a control method thereof. The electric-hydraulic proportional integrated controller comprises a two-way cartridge valve V1, a two-way cartridge valve V2, a two-way cartridge valve V3, a two-way cartridge valve V4, an operational amplifier module MK, a bidirectional working hydraulic motor MT, a two-position four-way electromagnetic directional valve V5, a two-position four-way electromagnetic directional valve V8, a two-position four-way electromagnetic directional valve V11, a two-position four-way electromagnetic directional valve V14, a three-position four-way electromagnetic proportional directional valve V6, a three-position four-way electromagnetic proportional directional valve V9, a three-positionfour-way electromagnetic proportional directional valve V10, a three-position four-way electromagnetic proportional directional valve V13, an overflow valve V7, an overflow valve V12, a hydraulic pumppux and a hydraulic pump puy; and the control method comprises the step that the hydraulic pump pux and the hydraulic pump puy are started when the controller is in the working state, at the moment,three working conditions including a stop working condition, a rising working condition and a falling working condition of the bidirectional working hydraulic motor MT appear. According to the electric-hydraulic proportional integrated controller and the control method thereof, the remote control, and automation and intelligent control are easy to realize.
