In the latest version of MATLAB Simulink (2020a), the interactive Control System Designer app does not work for MIMO system. It breaks the example and the video example. When selecting the MIMO decoupler in the architecture configuration, the error reports: "The model for 'rct_distillation_DM' must be single input, single output."
Also, in the Help page, it states that only SISO blocks are accepted for tuning.
At this moment, the only working MIMO example is https://www.mathworks.com/help/control/ug/decoupling-controller-for-a-distillation-column.html
I would like to ask whether this change is intended? Is there any alternative way to perform the interactive tuning as demonstrated in the example and the video example?
