Compared with traditional valve control systems, the independent metering valve control system (IMVCS) broke down the mechanical connection of the meter-in and meter-out orifices so that it increased the control degrees of freedom. More importantly, it achieved a more energy-efficient control mode for hydraulic system. This paper studied the dynamic characteristics of IMVCS based on fuzzy PID control algorithm. A controller included power amplifier module, voice coil motor (VCM) drive module, data acquisition module and CAN communication module was designed. A SYS/BIOS based embedded operating system was adopted in this controller for fast response. A host computer program based on CAN bus was developed to monitor status of the IMVCS. A series of experiments of displacement control and pressure control have been carried out, and results showed a good dynamic performance and huge potential of energy-efficient control.
