Application 2 Speed control system and pressure control system work individually (use diagram of Example 2).
Purpose: After the speed control operates in open loop for a period of time, adding into it the pressure control system
(PID instruction) for close loop control.
Explanation: Since the speed and pressure control systems are not interrelated, we have to structure a open loop for
speed control first following by a close loop pressure control. If you fear that the control instruction of the
pressure control system changes too fast, you can consider to add the instruction delay illustrated in
Application 1 into the control. See the control diagram below.
