Roadmap to MPT2

Introduction

MPT2 (alias MPT version 2.0) will be the next major relase of the Multi-Parameteric Toolbox after version 1.4.4 back in August 2004. Since then, development has been focused on improvements in numerical robustness, runtime efficiency of implemented algorithms, user interface and support of a broader class of solvers. Brand new algorithm for optimal control of PWA systems based on dynamical programming with PWA cost-to-go has been added as well, along with tools which aim at reducing complexity of resulting explicit solutions.

MPT2 will not just be a next release, it will be THE new version. It will provide sophisticated tools to model hybrid systems in an intiutive way, along with a powerfull graphical user interface and an extended Simulink library. We believe these changes will make the toolbox even more accessible for the control comunity.

Help us improve

Everybody is invited to participate in public testing of the forthcoming release. Snapshots of the version currently being developed are published on a daily basis and are available for public download. You can download latest builds from this location. Any feedback is very welcome. Feel free to send your comments, questions, or feature requests to our support center.

MPT version 2.0TR (testing release)

  • Complexity reduction - optimal and greedy merging of explicit controllers
  • Brand new algorihtm for optimal control of PWA systems is 3-10 faster than the old algorihtm
  • Improved numerical reliability
  • Speed improvements - majority of the code now runs up to 30-50% faster than in the previous version
  • Interface to MILP and MIQP solvers
  • Improved enumeration of extreme points and convex hulls
  • New mpLP solver
  • On-line MPC for LTI systems with boolean/integer inputs
  • Interface for CPLEX9
  • Many minor improvements (>30) and bug fixes
  • Extensive testing

MPT version 2.0PR (preview release)

MPT version 2.0 final

  • Updated Simulink interface with ability to use explicit controllers in RTW framework
  • Export of explicit controllers to C-code which can be linked to stand-alone applications.
  • Verification of hybrid systems
  • More examples
  • Support for CPLEX 8 MILP/MIQP solvers
  • Documentation update

Post 2.0 development

  • Visual modeling of hybrid systems
  • Possible support for non-fully dimensional polytopes
  • Your feature can be there. Just let us know.
