An introduction to cascade control. Using a comparison between a simple level control loop and level – flow cascaded loop this model can be used to develop a basic understanding of the uses and benefits of cascade control. By varying the flow to the two loops comparisons can be made between the two sets of control strategy. Contained within the model is a set of assignments explaining how to control each of the loops for optimum performance.
The model may be used for whole class teaching at a basic level, or for trainees individually, by using measurement of the Ultimate Gains and Periods to calculate the tuning constants in each situation.
The model includes User Guide, Assignments, and a comprehensive Trend Charts facility.
The graphic above is a screen shot showing two controller faceplates, the cascaded level and flow controller and has the 'User Guide' tab selected.
