(1) Electro hydraulic proportional servo technology will continue to be popularized and applied. The hydraulic servo system will change from the previous electro-hydraulic on-oE system and open loop proportional control system to the closed-loop proportional servo system. In order to adapt to this development, the pressure, flow, position, temperature, speed, acceleration and other sensors must be standardized. Computer interfaces should also be unified and compatible.

(2) The flow, pressure, temperature, oil stain and other values of the hydraulic system will be automatically measured and diagnosed. As the price of the computer is reduced, the monitoring system, including the central monitoring and automatic regulation system, will be developed. The standardization of computer simulation, especially the requirements for high-precision, "advanced" systems. Widespread application of electronic direct control components, such as electronic direct control hydraulic pumps, High torque cycloidal hydraulic motor The application of universal control mechanism, as well as the status and development of electromechanical integration of hydraulic products, are also issues that need to be discussed in the future.
