Simulation Example

Figure 5-2 OS picture of the example project

Despite the interaction between both manipulated variables MV1 and MV2 and the integral action of MV2 on PV2, both control variables PV1 and PV2 of the master controller can be controlled to their given set points independently of each other, which is a success of the described control concept. A “crosstalk” between the in- teracting control loops can mostly be avoided, e.g. the level PV2 (dark green) is only moved minimally during a set point step in SP1 (light blue). Specifics: Not only the current value of the level PV2 (dark green) is reaching the set point SP2 of the MPC (dark blue dashed) but also MV2 of the MPC (dark brown) in steady state, as MV2 is simultaneously the set point of the slave level controller.
