This book concerns existence and necessary conditions, such as Potryagin's maximum principle, for optimal control problems described by ordinary and partial differential equations. These necessary conditions are obtained from Kuhn-Tucker theorems for nonlinear programming problems in infinite dimensional spaces. Research: About half a century ago, the Russian mathematician L. Evolution partial differential equations are studied using semigroup theory, abstract differential equations in linear spaces, integral equations and interpolation theory. The optimal control problems include control constraints, state constraints and target conditions.

Fattorini graduated from the Licenciado en Matematica, Universidad de Buenos Aires in 1960 and gained a Ph. The author obtains these necessary conditions from Kuhn-Tucker theorems for nlinear programming problems in infinite dimensional spaces. The interview is a shorter version of the teaching statement. This allows for the formation of the dynamic interdependency between both types of innovations. In addition, we can calculate generalized solutions when the original problem lacks of minimizers. The method is much different from standard methods. Numerical examples are presented to illustrate the results.

The change of the state dimension has the character of a jump and is modeled by an impulsive hybrid system. These necessary conditions are obtained from Kuhn—Tucker theorems for nonlinear programming problems in infinite dimensional spaces. The interest is placed on minimization of the tracking error in the multiagent leader-follower model. The author establishes existence of optimal controls for arbitrary control sets by means of a general theory of relaxed controls. It is proved that the family of controllers considered solves the problem of approximate controllability for the infinite dimensional system.

In particular, this paper deals with applications of the above-mentioned continuity and approximability to some hybrid control systems and to the classical sliding mode control processes. The analysis uses the reliability and the discrete local efficiency of the a posteriori estimator as well as quasi-orthogonality properties as essential tools. We prove reliability and efficiency of the error estimator and provide a bulk criterion for mesh refinement that also takes into account data oscillations and is realized by a greedy algorithm. The Linear-Quadratic Problem: Existence and Uniqueness of Optimal Controls; 2. We prove that accumulation points of sequences generated by the first method are extremal for the discrete problem, and that relaxed accumulation points of sequences of discrete controls generated by the second method are admissible and extremal for the continuous relaxed problem.

The motivating example is cottonwood-salt cedar competition, where the effect of disturbance in the system such as flooding is taken to be a control variable. See the seller's listing for full details. Firstly, the existence of piecewise continuous mild solutions for the original fractional impulsive control system is established.

The classical control problem is then discretized by using a finite element method in space and the implicit Crank-Nicolson midpoint scheme in time, while the controls are approximated by classical controls that are bilinear on pairs of blocks. With this method we can determine either the existence or lacking of minimizers. Metric, Banach, and Hilbert Spaces; 2. In this paper, we study a specific optimal control problem associated with a multiagent dynamic system.

Fuel Optimal Soft Landing of a Space Vehicle: Identification of the Optimal Trajectory; 4. Applications include nlinear systems described by partial differential equations of hyperbolic and parabolic type and results on convergence of suboptimal controls. Convergence of the cost, optimal controls, and optimal states of the finite dimensional, reduced-order, optimal control problems to the original optimal control problem is analyzed. In the two-dimensional case we show that the linear feedback law provides a local exponential stabilization of the Navier--Stokes equations. This result is applied to deriving a control law that stabilizes a part of the variables describing a rotating rigid body endowed with a number of elastic beams.

The result has been achieved by means of the classical Hamilton-Jacobi equation, suitably modified in order to consider the peculiar constraint of the problem. This book is on existence and necessary conditions, such as Potryagin's maximum principle, for optimal control problems described by ordinary and partial differential equations. These comparisons are carried out for mechanically induced phase transformations in a shape-memory alloy rod.

Time and norm optimal controls: A survey of recent results and open problems, Acta Matematica Scientia 31B 2011 2203-2218. Abstract minimization problems: the minimum principle for the time optimal problem; 4. Relaxation control for a class of semilinear impulsive controlled systems is investigated. Optimal Control: Minimum Drag Nose Shape in Hypersonic Flow. The essential of this proposal is the transformation of a non-linear, non-convex optimal control problem into an equivalent optimal control problem with linear and convex structure. Consideration was given to the hybrid control systems with autonomous switching, as well as the corresponding problems of the hybrid linear-quadratic optimal control based on the recently suggested principle of maximum. Fattorini studies evolution partial differential equations using semigroup theory, abstract differential equations in linear spaces, integral equations and interpolation theory.

The paper proposes an effective computational procedure for the above optimal tracking control problem in a multiagent setting. In particular, we also solve a longstanding open problem of J. The latter can be effectively applied to vide classes of variable structure control systems. The optimal control problems include control constraints, state constraints and target conditions. An alternative approach is represented by continuous-time vintage capital models that explicitly involve the equipment lifetime and are described by nonlinear integral equations. Using this decomposition, we show that the feedback law can be expressed as a function only of Py. The paper is devoted to stability and stabilization of a class of evolution equations arising from mathematical modeling of hybrid mechanical systems with flexible parts.
