2.1 Description of the control function

PID-IMM application control scheme aims to manage pump speed according to flow reference and pressure
feed-back. As simplification, the motor speed is used to control the pump flow rate.
Hereunder the general diagram of the control system:

Parameters
The system architecture is composed by 3 main layers:
• Input interface
• PID-IMM Controller
• ADP200 Speed control
PID-IMM controller is the core of the application. The control needs as input the Pressure feedback measured
from external sensor, the pressure reference and the speed reference. These information are processed by
the reference and the feedback Input interfaces.
The Input Interface gives the user the possibility to set properly the references and the pressure feedback
signals by using different ways (Analog / Digital input output or CANbus Field-bus).
