ShapeIt is a dedicated loopshaping tool for motion systems.

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
