Abstract: The energy-saving, fast response and high accuracy electro-hydraulic control systems are required by some mechanic equipments. The aimed system is constructed with one constant power and constant pressure pump, two integrated electro-hydraulic servo motors and one single chip microcom puter cascade human being intelligence simulating controller. The pump is the key power equipment for energy-saving, the motor is the key actuator for fast response, the control mode of simulating human being intelligence is the key control strategy for high accuracy.

Key words: Cascade control, Electro-hydraulic control system, Energy-saving, Fast response, High accuracy, Intelligent control
