| Abstract: | Against poor velocity performance being controlled by ordinary flow control valve and inefficiency of operation,a method of hydraulic cylinder velocity control operated by high-speed on-off valves was proposed and the PWM signals were generated from the freescale 56F8300 hybrid controller.The 56F8300 hybrid controller＇s edge-aligned operation conducted by PWM module and center-aligned function implemented the ordinary PWM control from double-rod hyolraulic cylinder and PWM differential control,i.e two methods concerned. |
