RODRIGUEZ, SA; DE-LEON, J; BARAJAS-FERNANDEZ, J  e  RIVERA-TREJO, F. Adaptive observer for open prismatic tanks. Universidad y ciencia [online]. 2010, vol.26, n.3, pp.299-305. ISSN 0186-2979.

The design of an adaptive observer is presented in this paper. This is a computational sensor that will be used to estimate the inflow and several parameters that are difficult to measure in open tanks, such as the discharge coefficient. A mathematical model for an open tank is proposed by means of a nonlinear system. Furthermore, sufficient conditions are given to guarantee the convergence of the observer. Simulation results indicate possible applications in water tanks.

Palavras-chave : Open tank; nonlinear system; adaptive observer; convergence; discharge coefficient.
