Numerical Methods for Optimal Control Problems with State Constraints

While optimality conditions for optimal control problems with state constraints have been extensively investigated in the literature the results pertaining to numerical methods are relatively scarce. This book fills the gap by providing a family of new me

Preface

The material presented in this book is the result of the author's work at the Interdisciplinary Centre for Process Systems Engineering at Imperial College, London. In initial stages, for the period of first nine months, the work was supported by the British Council, then directly by the Centre where the author was employed until August 1998. Originally, the aim of the work was to provide numerical methods for optimal control problems with state constraints. At that time, that is, in early 1990s, the methods available for these problems (with the exception of the work [42], which is discussed later) were either the methods based on full discretization (parametrization of state and control variables), or they were function space algorithms (where decision variables were measurable functions). The first group of methods assumed a p r i o r i discretization of system equations, and thus exc
