ShapeIt is a dedicated loopshaping tool for motion systems.

Contents

Screenshots

ShapeIt is designed for Matlab. Here are some screenshots (click to enlarge):

Requirements

  • Matlab 7.04 or newer
  • Control System Toolbox
  • C-compiler (Matlab LCC, gcc, or any other compiler)
  • To use the optimization: Global Optimization Toolbox (from R2010a onwards) / Genetic Algorithm Direct Search Toolbox (up to R2009b)

Download

The current version is v0.14.

Release v0.12

Release v0.13

Release v0.14

Full version:*
ShapeIt_v0.12

Full version:*
ShapeIt_v0.13

Full version:*
ShapeIt_v0.14

Educational version:**
ShapeIt_student_version_v0.12

Educational version:**
ShapeIt_student_version_v0.13

Educational version:**
ShapeIt_student_version_v0.14

Some important changes:

  • compatible with Matlab FRD objects
  • improved computation of unwrapped phase
  • improved margin computations
  • unit disc (0dB) in Nyquist plot
  • wrapping of Nichols chart possible
  • improved controller discretization
  • small bug-fixes

Some important changes:

  • improved labels for data cursors in all plots
  • frequency data available in Nyquist and Nichols data cursor
  • loading plants from file improved
  • better usability of data-loading functionality
  • better looks when used on Linux platforms

Some important changes:

  • added extra 4th order example plant with adjustable parameters
  • updated DCTools for compatibility with dSpace
  • solved occasional stability-issue for discretized controller
  • minor adjustments for plants with many RHP zeros and/or poles
  • minor bug-fixes

* Full version contains optimization aid based on genetic programming:

  • contact the program maintainer if you want to try it (file is password protected for educational reasons)
  • requires the "Global Optimization Toolbox" (formerly known as "Genetic Algorithm Direct Search Toolbox")

** Educational version has no optimization aid.

Installation

  • Unzip files into a directory e.g. C:\Program Files\matlab704\toolbox\shapeit
  • Goto this directory in Matlab and run: shapeit_setup_runonce
  • Installation is ready now, the application can be started by running: shapeit

If you have any trouble installing or using ShapeIt, please read the <a href="faq_of_shapeit.htm">FAQ</a> first.

Feedback

Please send bugs, problems, suggestions for future releases etc. to Gert Witvoet.
