Reconfiguration of the 3-Tank System

Abstract

The 3-Tank experiment is shown in Fig. 16.1. It consists of three tanks, which are connected via the valves u₂, u₃ and u₄. Pumps can bring water into the left and the right tank, but not into the middle tank. The control objective is to maintain a certain level in the middle tank, such that the outflow z is constant. The relevant components of the system are shown in Fig. 16.2. The system is very similar to the one defined in the original publication of the 3-Tank Benchmark Problem by Heiming and Lunze [1999]. However, because a real experiment is used here, the identified parameters have to be used.
