Process Control: Modeling, Design, and Simulation

M2.2. Open-Loop Simulations

You now have enough information to generate an open-loop simulation. The Clock,simout,step, and Transfer Fcn blocks can be dragged to a model (.mdl) workspace, as shown in Figure M2-5a. Renaming the blocks and variables, and connecting the blocks, results in the model shown in Figure M2-5b. The transfer function studied is the Van de Vusse reactor (see Module 5).
