Description:  OCCAL. A mixed symbolicnumeric optimal control calculator The numerical solution of optimal control problems by indirect methods (such as multiple shooting or collocation) requires a considerable amount of analytic calculation to establish a numerically tractable system. These analytic calculations, though being rather tedious in realistic examples, are nowadays mostly still done by hand – and thus prone to calculation errors. The paper aims at automating this analytic processing to a reasonable extent by means of a modern symbolic manipulation language (here: REDUCE). In its present stage of development the package OCCAL (mnemotechnically for Optimal Control \(underline{ ext{CAL}}\)culator) permits an interactive use, covering tasks like automatic determination of control and, in case of a singular control, of its order.par In simpler problems, the present version of OCCAL automatically produces the full subroutine input for a MULtiple shooting code (MULCON) with adaptive numerical CONtinuation.par In more complicated problems where singular subarcs may occur or where the sequence of subarcs of the optimal trajectory is unclear OCCAL is a significant help in reducing analytic preprocessing. Examples illustrate the performance of OCCAL/MULCON.
