Applied fuzzy summability techniques

Fuzzy Logic Applied to Damage Characterization through SHM Techniques

Fuzzy Logic is an Artificial Intelligence technique that is dedicated to the construction of meta-models based on the human comprehension of a specific phenomenon. When a person is capable to understand such a phenomenon, it is possible to determine the response of the plant based on subjective rules associated to the system under study. This contribution focus on the use of fuzzy logic techniq...

On Some Summability Spaces of Sequences of Fuzzy Numbers

In this article we introduce and study the notions of ( , ) s v r  -lacunary strongly summable, ( , ) s v r  Cesàro strongly summable, ( , ) s v r  statistically convergent and ( , ) s v r  -lacunary statistically convergent sequence of fuzzy numbers. Consequently we construct the spaces   ( , ) F sv r L  ,   1 ( , ) F sv r   ,   ( , ) F sv r S  and   ( , ) F sv r S  respecti...

Some Summability Spaces of Double Sequences of Fuzzy Numbers

In this article we introduce and study the notions of double -lacunary strongly summable, double  Cesàro strongly summable, double  statistically convergent and double  -lacunary statistically convergent sequence of fuzzy numbers. Consequently we construct the spaces   2 F L  ,   2 F   ,   2 F S  and   2 F S  respectively and investigate the relationship among these spaces. F...

Nonlinear Optimal Control Techniques Applied to a Launch Vehicle Autopilot

This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin Approximation (SGA), is used to obtain an approximate optimal solution. Simulation results invo...
