Three-Tank-system (Amira DTS200)
|
The laboratory experiment "Three-Tank-System DTS200" includes the technical realization of a nonlinear multi input-multi output system (two inputs, two outputs) with two actuators and a digital controller (nonlinear control and decoupling).
The nonlinear controlled system consists of three plexiglass cylinders T1, T2 and T3 with the cross-sectional area A which are interconnected in series by two connecting pipes. The liquid (distilled water) leaving T2 is collected in a reservoir from which pumps 1 and 2 supply the tanks T1 and T2. All three tanks are equipped with piezo-resistive pressure transducer for measuring the level of the liquid. A digital controller controls the flow rate Q1 and Q2 such that the levels in the tanks T1 and T2 can be preassigned independently. The level in tank T3 is always a response which is uncontrollable. The connecting pipes and the tanks are additionally equipped with manually adjustable valves and outlets for the purpose of simulating clogs as well as leaks.
The documentation of the base model DTS200 includes sections for assembly and start-up and the technical data.
