A conical tank in which the diameter changes with the tank height, allows the use of feedback control used in complex nonlinear systems, such as adaptive control. This project modified an existing system of two interacting tanks by inserting a removable solid cone into one of the tanks. This modification created two new nonlinear configurations, one of which had a discontinuity. Optimal control...

The buckling of aboveground circular steel tanks with conical roof is considered in this paper. The specific source of loads investigated is wind action during hurricane storms in the Caribbean islands. The structure is modeled using a finite element discretization with the computer package ALGOR. Bifurcation buckling of the shell is computed for a given static wind pressure distribution. Then ...

Scientific discovery implies exploring a vast search space of possible hypotheses in the hope of finding a model befitting the available data. Our present aim is to use Genetic Programming (GP) and a representation involving both crisp numbers and fuzzy quantity spaces to learn models of simple physical systems from a set of imperfect and incomplete data. We use the ECJ framework, to learn mode...

The aim of this work is to compute a level backstepping control strategy for a coupled tanks system. The coupled tanks plant is a component included in the water treatment system of power plants. The nonlinear-model of the process was designed and implemented in MatlabSimulink. The advantages of the control method proposed is that it takes into consideration the nonlinearity which can be useful...
