Configuration of MPC with Slave Controller

4.1Starting Point
The starting point is the standard connection of the MPC with its actuators. The structure of the following example corresponds to the control of product quality (CV1) and level (CV2) in a reactor as mentioned in section 2.3.4. However, this ex- ample is not a realistic simulation of a real reactor.

4.2Connection in CFC
Now, a stabilizing PID controller is inserted for the integral sub process. In principal this control structure is a cascade consisting of an MPC as master controller and the stabilizing
The equality of the controlled variable of the master controller (i.e. the correspond- ing MPC control channel) and the controlled variable of the slave controller is the only special feature in the present case.
