  2. 2. A Newton Method for Solving Non-Linear Optimal Control Problems with General Constraints

    University dissertation from Linköping : Linköping University

    Author : Henrik Jonson; Linköpings universitet.; Linköpings universitet.; [1983]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Newton method; Non-linear; Control problems;

    Abstract : Optimal control of general dynamic systems under realistic constraints on input signals and state variables is an important problem area in control theory. Many practical control problems can be formulated as optimization tasks, and this leads toa significant demand for efficient numerical solution algorithms. READ MORE
