User's Guide for SNCTRL

by Philip E. Gill, Elizabeth Wong


SNCTRL is an optimal control interface for the software package SNOPT, written in Fortran 2003 and built and tested on version 7.5-2 of SNOPT. The optimal control problems are solved by discretizing and transforming the problem into a finite-dimensional nonlinear program (NLP). Several methods exist for discretizing the problem including single shooting, multiple shooting and collocation; SNCTRL implements a collocation method. Once the problem has been discretized, SNCTRL sets up the NLP and the required data structures for SNOPT.
