Optimal control links

• RIOTS 95 a MATLAB toolbox for solving optimal control problems.
• GESOP and ASTOS GESOP (Graphical Environment for Simulation and Optimization) is a software system for trajectory analysis and design of user defined, controllable dynamic systems governed by a set of ordinary nonlinear differential equations, associated boundary conditions, path constraints and cost functions. Uses direct collocation methods TROPIC and SOCS (Sparse Optimal Control Software) from Boeing company, and multiple shooting method PROMIS. ASTOS is aimed for launch and reentry of aerospace vehicles, it includes GESOP.
• DIRCOL A direct collocation method for the numerical solution of optimal control problems.
• Reports from CAAM related to control and numerical solution of optimal control problems.
• TOMS/733 TOMP
• TOMLAB /DIDO Optimal control problem solver for Matlab, uses TOMLAB /SNOPT.
• SOCS, SPRNLP
• MINOPT, (C. F. Floudas)
• Miser MISER3 is a suite of Fortran programs for solving continuous and discrete-time optimal control problems, optimal parameter selection problems, or a combination of both, subject to general constraints. The method used is based on the idea of control parametrization in which the controls are approximated by piecewise constant or piecewise linear (continuous) functions defined on suitable partitions of the time interval. The code then converts the problem into a nonlinear programming problem which is solved using a sequential quadratic programming algorithm.

Simulation environments and models

• Mathworks Simulink.
  • Simcar sells a powertrain library that models a vehicle in longitudinal motion that is collected as a set of equations for Simulink.
• Amesim a component based simulation environment for vehicular applications.
• The Modelica standard for an object oriented simulation environment. The two most well known companies that sell Modelica tools are
  • Dynasim vendor of the only simulation engine that supports Modelica.
  • MathCore vendor of MathModelica a Mathematica interface to Modelica.
• HPS (High performance systems) sells a simulation program package called STELLA that is used to teach system based thinking to students.
• Ricardo have developed the one dimensional gas dynamic simulation tool named wave. They have also developed and are maintaining the Powertrain and Engine libraries for the EASY5 simulation environment developed by BOEING.
• DADS Multi-Body dynamics.
• MOTHER (MOtor THERmodynamics) is a "virtual powerplant" simulation software for propulsion systems.
• Advisor is a hybrid electric vehicle (HEV) simulation model written in a widely used software environment called MATLAB/Simulink. This tool tests the impact of changes in vehicle components, such as catalytic converters, climate control systems, alternative fuels or other modifications that might impact fuel economy or emissions. The user can alter simulation results by selecting vehicle component types, sizes and parameters.
• Engine Simulation Program esp from Stanford. This package is based upon Lumley's introductory book on "internal combustion engines", published in 1999 by the Cambridge University Press.

Matlab like programs (sometimes clones)

• Octave is generally considered a Matlab clone. The main author is, John W Eaton, who describes it as "mostly compatible with Matlab". It is developed under GNU it is freely distributable under GPL. A GNU C++ compiler is needed to compile the source from scratch, but Unix/Linux and Windows binaries are available.
• Scilab, uses a Matlab-like syntax, and its creators, the Scilab Group at INRIA (French acronym for National Institute for Research in Computer Science and Control) describe it as "similar but not a clone". Aimed at scientific applications in particular, it offers application modules for system control and signal processing; an online dynamic link with Fortran or C routines; a Maple interface, and Scicos, a flowchart-style dynamic system simulator equivalent to Simulink. It's freely distributed as source code or as binaries for Unix/Linux, Windows and Mac. Other programs available as freeware include Tela (TEnsor LAnguage) and Euler. Tela is a Fortran-style "numerical computing environment mainly targeted for numerical simulation pre- and postprocessing work". Euler is a numerical laboratory with a programming language ("not a MatLab clone, but very similar"); an unusual feature is its ability to perform interval arithmetic, where variables are number ranges.
