Application 2:
Speed control system and pressure control system work individually (use diagram of Example 2)
C
ontrol purpose:
After the speed control operates in open loop for a period of time, adding pressure control system
(PID instruction) to perform a close loop control.
Control properties:
Since the speed and pressure control systems are not interrelated, we have to structure an open
loop for speed control first following by a close loop pressure control. If users afraid that the
pressure control system changes excessively, consider adding the SC ramp-up function illustrated
in Application 1 into this control. See the control diagram below.
