ShapeIt is a dedicated loopshaping tool for motion systems. It depicts all the relevant information and transfer functions for loopshaping a controller in a single window, making life of a control engineer a little bit easier. The full version even comes with an automated optimization tool. ShapeIt runs under Matlab, version 7.0.4 and higher.

ShapeIt has been first presented to the public at the 2006 IEEE ICCA.

Screenshots

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

Requirements

  • Matlab 7.0.4 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 v0.16. For older versions, please see Older versions.

Release v0.16

Full version:*
ShapeIt_v0.16

Educational version:**
ShapeIt_student_version_v0.16

Some important changes:

  • also added "double integrator" to DCtools (Simulink blocks)
  • solved saving of the wrong blocks after pressing "Save to Simulink" button
  • improved mexall to be able to compile from a different directory

* 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 FAQ of ShapeIt first.
