This site describes a Double tank problem variant with three binary controls instead of only one control.
The mixed-integer optimal control problem is given by
These fixed values are used within the model.
If the problem is relaxed, i.e., we demand that be in the continuous interval instead of the binary choice , the optimal solution can be determined by means of direct optimal control.
The optimal objective value of the relaxed problem with is . The objective value of the binary controls obtained by Combinatorial Integral Approimation (CIA) is .
