Optimal control : calculus of variations, optimal control theory, and numerical methods by
Roland Bulirsch(
Book
)
14 editions published between 1992 and 1993 in English and German and held by 204 WorldCat member libraries worldwide
"Optimal Control" reports on new theoretical and practical advances essential for analysing and synthesizing optimal controls of dynamical systems governed by partial and ordinary differential equations. New necessary and sufficient conditions for optimality are given. Recent advances in numerical methods are discussed. These have been achieved through new techniques for solving largesized nonlinear programs with sparse Hessians, and through a combination of direct and indirect methods for solving the multipoint boundary value problem. The book also focuses on the construction of feedback controls for nonlinear systems and highlights advances in the theory of problems with uncertainty. Decomposition methods of nonlinear systems and new techniques for constructing feedback controls for state and control constrained linear quadratic systems are presented. The book offers solutions to many complex practical optimal control problems

Computational optimal control by
Roland Bulirsch(
Book
)
16 editions published in 1994 in English and held by 192 WorldCat member libraries worldwide
There is public agreement that all resources should be used sparingly both from the point of view of economy and ecology. Therefore optimization is the tool of choice in controlling industrial and economic processes. This book collects the reviewed papers of the ninth IFAC Workshop on Control Applications of Optimization, which took place in Munich in September 1992. Highlights from the ensuing discussions have been incorporated by the authors. The volume reflects the state of the art in the application of finite and infinite dimensional optimization to open and closed loop control problems. Its spectrum ranges from the oretical foundations of the proposed methods and numerical implementations of algorithms to applications to real world problems. Emphasis lies on the solution of practical industrial problems in aerospace, mechanical and electrical engineer ing, manufacturing technology and economic and manage ment systems. Among the theoretical papers are contributions from non linear programming (interior point methods, large structured problems, nonsmooth problems, and vectorvalued criteria) and optimal control (multipoint boundary value problems, state and control constraints, feedback solutions, differen tialalgebraic systems and differential games)

9 editions published between 1989 and 1990 in English and held by 161 WorldCat member libraries worldwide
Numerical simulation and modelling of electric circuits and semiconductor devices are of primal interest in today's high technology industries. At the Oberwolfach Conference more than forty scientists from around the world, in cluding applied mathematicians and electrical engineers from industry and universities, presented new results in this area of growing importance. The contributions to this conference are presented in these proceedings. They include contributions on special topics of current interest in circuit and device simulation, as well as contributions that present an overview of the field. In the semiconductor area special lectures were given on mixed finite element methods and iterative procedures for the solution of large linear systems. For three dimensional models new discretization procedures including software packages were presented. Con nections between semiconductor equations and the Boltzmann equation were shown as well as relations to the quantum transport equation. Other issues discussed in this area include the design of simulation programs for semiconductors, vectorcomputers, and interface problems in several dimensions. Topics discussed in the area of circuit simulation include the index classification of differentialalgebraic systems, connections with illposed problems, and regularization techniques. Split discretization procedures were given for the efficient calculation of periodic solutions of circuits taking into acount the latency. Homotopy methods and new numerical techniques for differentialalgebraic systems were presented, and im provements of special numerical methods for standard software packages were sug gested.

Progress in today's hightechnology industries is strongly associated with the development of new mathematical tools. A typical illustration of this partnership is the mathematical modelling and numerical simulation of electric circuits and semiconductor devices. At the second Oberwolfach conference devoted to this important and timely field, scientists from around the world, mainly applied mathematicians and electrical engineers from industry and universities, presented their new results. Their contributions, forming the body of this work, cover electric circuit simulation, device simulation and process simulation. Discussions on experiences with standard software packages and improvements of such packages are included. In the semiconductor area special lectures were given on new modelling approaches, numerical techniques and existence and uniqueness results. In this connection, mention is made, for example, of mixed finite element methods, an extension of the BaligaPatankar technique for a three dimensional simulation, and the connection between semiconductor equations and the Boltzmann equations

Variational Calculus, Optimal Control and Applications was the topic of the 12th Baltic Sea conference, traditionally an important meeting place for scientists from Eastern and Western Europe as well as the USA. This work contains contributions presented at that conference and addresses four problem complexes mostly motivated by practical problems. The starting points are often questions taken from flight dynamics. The first chapter deals with existence theory and optimality conditions needed for justification of, and used in, numerical algorithms. Analysis and synthesis of control systems and dynamic programming are presented in the second chapter. A modern interpretation of a solution of the HamiltonJacobiBellman equation is given. This is closely connected to the question of realtime or feedback control. Recent advances in the field of numerical methods and their applications to flight path optimization and fluid dynamics follow. The reader will find nonlinear programming methods, accelerated multiple shooting, homotopy and SQP methods. A wide variety of applications to mechanical and aerospace systems concludes this work: space flight problems, mobile robot controlling, geometrical extremal problems, fluid transport, fluid waves and human sciences

Computerassisted systems have long since penetrated the operating room. Their functions include pre and intraoperative imaging, image processing, modeling, simulation, navigation, and robotics. Computers help run the "surgical cockpit." They are critical in pre and intraoperative process optimization, workflow management, and for information integration in the surgical suite
