1  Overview of Rltool for Scilab

1.1  Description

RLTOOL is a completly graphics based tool for designing compensators for SISO continuous plants. An attempt has been made to provide most of the features available in a utility of similar name which is available with a well known commercial software.

1.2  Targetted users

The intention behind developing this package is to provide a free and easy to use tool for students taking a first course in control engineering. Learning is more fun if computer based teaching is used to supplement classroom lectures. It is intended to make RLTOOL as simple and user friendly as possible and yet have some powerful and innovative features.

1.4  How to install RLTOOL

1.4.1  For Linux users

I assume that you have obtained the file rltool1.*.tar.gz and have saved it at the location ``PATH'' on your computer. For example, I have downloaded the file in my home directory /home/ishan , hence PATH = /home/ishan
  1. Unzip the zipped file. The fact that you are reading this README shows you completed step 1 :) This has generated a directory called rltool in my home directory. So my PATH is /home/ishan/rltool

  2. Start scilab

  3. At the scilab prompt, type
    --> exec /home/ishan/rltool/builder.sce
    you need to do this only ONCE. This "compiles" the *.sci files and generated binary files.

  4. To "load" rltool into Scilab, type the following at the Scilab prompt
    --> exec /home/ishan/rltool/loader.sce
    you will need to "load" rltool every time you start a FRESH scilab session, or issue an explicit "clear" instruction at the Scilab prompt

  5. Type rlt() to start using rltool

  6. If you are indeed the root, you may want to "build" rltool once so that multiple users can access it simultaneously

1.4.2  For Windows users

I assume that you have obtained the file rltool1.*.tar.gz and have saved it at the location ``PATH'' on your computer. For example, I have downloaded the file in my home directory C:\ishan , hence PATH = C:\ishan
  1. Unzip the zipped file. The fact that you are reading this README shows you completed step 1 :) This has generated a directory called rltool in my home directory. So my PATH is C:\ishan\rltool.

  2. Start scilab

  3. At the scilab prompt, type
    --> exec C:\ishan\rltool\builder.sce
    you need to do this only ONCE. This "compiles" the *.sci files and generated binary files.

  4. To "load" rltool into Scilab, type the following at the Scilab prompt
    --> exec C:\ishan\rltool\loader.sce
    you will need to "load" rltool every time you start a FRESH scilab session, or issue an explicit "clear" instruction at the Scilab prompt
  5. Type rlt() to start using rltool
  6. If you are indeed the ADMIN, you may want to "build" rltool once so that multiple users can access it simultaneously

Once installed (see the README file accompanying this package), RLTOOL can be invoked by typing 'rlt()' on the Scilab command prompt.
