Many real-world systems contain uncertainties and with time-varying delays, also, they have become larger and more complicated. Hence, a new decentralized variable structure control law is proposed for a class of uncertain large-scale system with time varying delay in the interconnection and time varying unmatched uncertainties in the state matrix. The proposed decentralized control law for the...

Transport of Bose-Einstein condensates in magnetic microtraps, controllable by external parameters such as wire currents or radio-frequency fields, is studied within the framework of optimal control theory (OCT). We derive from the Gross–Pitaevskii equation the optimality system for the OCT fields that allow to efficiently channel the condensate between given initial and desired states. For a v...

In this paper, some of the relationships between optimal control and statistics are examined. In a series of earlier papers, we examined the relationship between optimal control and conventional splines and between optimal control and the statistical theory of smoothing splines. In this paper, we present a unified treatment of these two problems and extend the same framework to include the conc...

Abstract T he return of capital is fundamental to the intertemporal allocation of resources by changing the consumption behavior and capital accumulation over time. Taxation on return of capital increases the marginal product of capital, meaning that capital stock is lower than when capital is not taxed, which results decreased growth and welfare in steady state. This pape...

We prove a local existence result for the manoeuvrability control of a submarine. The problem is formulated as an optimal control problem with a nonlinear and highly coupled system of ODEs for the state law, a Lagrange type cost function, and nonlinear controls which take values on a convex and compact subset of R. Finally, the existence of solution for this problem is obtained by applying a re...

In the theory of mathematical optimization one try to find maximum or minimum points of functions depending of real variables and of other functions. Optimal control theory is a modern extension of the classical calculus of variations. Euler and Lagrange developed the theory of the calculus of variations in the eighteenth century. Its main ingredient is the Euler equation which was discovered a...
