The AC control system of the 4m planer is retrofitted with PC for table automatic cycle, jogging forward and jogging backward, automatic feed and withdraw.
In this algorithm, the mechanism of dropping packet is replaced with ECN marks. It USES the PID controller as feed-backward compensation to ensure the stability of the system.
