Benchmark C09 Fuzzy Control of a Two Tank System is a tribute to the method of fuzzy control. A two-tank system in a specific configuration is characterized by nonlinear balancing ODEs, including characteristics of the liquid (laminar, turbulent, friction). Two fuzzy controllers (one using singletons) should be implemented as discrete systems.

The benchmark requires implementation of the fuzzy controllers and 3-D visualisation and various use of the fuzzy controllers for control of the two-tank system.

From educational viewpoint, the benchmark introduces to fuzzy control and its implementation in continuous systems. The two-tank system could be described by physical modelling.
