==> INTRODUCTION

  COSY_PAK is set of packages and notebooks for classical control and 
(some) modern (state space) control analysis and design methods. The
notebooks in COSY_PAK follow a typical `Control Engineering I' course
taught at many universities around the world for the junior/senior 
level undergraduates. There is NO FEE to use COSY_PAK but certain 
responsibilities are expected of the user (see Copyright notice in the 
README file included below). For starters e-mail / FAX / Mail (Post) 
the registration form included in the README file.

COSY_PAK is available via `anonymous ftp' from

          mishna.esys.cwru.edu (INTERNET No : 129.22.40.23) 

in the /pub directory. 

P.S.: A typical ftp session in UNIX is given after the README file.

is given at the end of this file.

**********************************************************************

--> Changes in Version 0.9 (update from v0.81 to v0.9)

	In this version, we have revised COSY_PAK to take advantage of 
the more robust signal processing functions available in Mathematica v2.1.  
Since Mathematica 2.1 provides a better  and  working 
LaplaceTransform and InverseLaplaceTransform functions than 
Mathematica v2.0 did, we adopted them. This has made COSY_PAK 
smaller. Thus Brian Evans' Signal Processing packages that supported 
the LaplaceTransform  and InverseLaplaceTransform functions in the 
COSY_PAK v0.81 are no longer needed directly by COSY_PAK v0.9. For 
power users who  use Signal Processing we still recommend the use of the very  
fine  Brian Evans package on Signal Processing (available at 
the anonymous  ftp site gauss.eedsp.gatech.edu  or  IP # 130.207.226.24).  On  
the  downside, the disadvantage of this update 
can be that Mathematica 2.1 requires more runtime resources than its 
previous version. 


***********************************************************************	
--> For Mathematica 2.0 users
	
	We have included the LaplaceTransform package from Mathematica 2.1 in  
the directory `For_2.0'. Please move all files and directory under For_2.0 into  
the Calculus directory under Mathematica Packages directory. 

**************************************************************************
	    
--> Introduction
   
    This is an unsupported release of COSY_PAK - a COntrol SYstems 
analysis PAcKage for symbolic control systems analysis using 
Mathematica 2.1. Classical control systems analysis and design methods and some  
modern control systems methods have been implemented in this package. 
    
    This package and the attendant notebooks were developed on a 
NeXT (TM) computer (a UNIX based workstation). They have been 
used as a supplementary teaching aid along with  standard control 
engineering texts (Ogata [1991], Phillips and Harbor [1991]) for 
undergraduate courses in `Control Engineering I' taught at the Systems 
Engineering Department of CWRU. In addition to the NeXT, they have 
also been tested successfully on Apple Macintosh computers (TM), and, 
IBM PC's (TM) running MS Windows(TM). We would be very much interested 
to hear from you if you or anybody you know uses this software on 
platforms not mentioned above. IBM users however will have to 
evaluate the notebooks first to visualize the graphics.

    Once installed (see below for instructions), this  collection  of  
Mathematica  packages  can be loaded by any user. Bundled with the 
packages are many notebooks ("COSY_Notes") which demonstrate  
the functionality of these packages. The notebooks follow a plan of 
many fine, standard, undergraduate Control Engineering text books 
listed in the references. Examples used in these notebooks have 
been collected from the various references given at the end of this 
file. The contents of the notebooks in the "COSY_Notes" directory are

--> Compressed Files

        The files that contain  a  complete set of the COSY_PAK v0.9
packages and Notebooks for Mathematica are:

 COSY_PAK_09.tar.Z     		compressed tar file for Unix systems
	
 COSY_PAK_09.sit.hqx     	compressed sit file for Macintosh 
 				systems and encoded by BinHex 4.0 
				format (requires the   shareware
				 Stuffit file v 1.5.1 or higher). 
	
 COSY_PAK_IBM_09.zip    	zip file for the IBM PC running MS-DOS
    
     Once expanded the Mathematica files can also be used on 
Macintosh / IBM PC / Unix systems also.


--> Installation of COSY_PAK

 o In UNIX Command line type the following command:

      zcat COSY_PAK_09.tar.Z | tar xvf -

 o In Macintosh open the .sit.hqx file using the shareware
    Stuffit v 1.5.1 or higher.
  
 o In IBM Command line type the following command:

      pkunzip -o -d COSY_PAK_IBM_09.zip

NOTE: This .zip file was zipped by zip utility v2.0. You must use 
pkunzip version 2.0 or  higher to unzip it.  IBM PC's may limit the 
directory name characters to eight. In that event type "pkunzip -o -d 
COSY_PAK.zip.  You can also unzip the COSY_PAK_IBM_09.zip file on any 
Unix machine if you have unzip utility on it.


     Uncompressing and untarring "COSY_PAK_09.tar.Z" or unzipping 
"COSY_PAK_IBM_09.zip" will create a directory called "COSY_PAK".
         	
Once the files are expanded you should see a single directory 
"COSY_PAK" containing the following three files, four 
sub-directories and their contents:

SUB-DIRECTORIES in "COSY_PAK":  
  COSYPAK    - contains control tool box packages 
  MANUAL     - COSY_PAK manual in .ps, .rtf, .txt, and .wn formats. 
  COSY_Notes - contains notebooks 
  For_2.0    - contains Laplace transform package from Mathematica 2.1
  		For Mathematica 2.0 users.	 
    		
FILES in directory "COSYPAK":
  chap1.m   chap2.m   chap3.m  chap4.m  chap5.m   chap6.m  chap7.m
	
FILES in directory "COSY_Notes":
	01_Introduction.ma	  
	02_Math_Model.ma
	03_1_Transient_Response.ma   
	03_2_Transient_Response.ma   
	03_3_Transient_Response.ma   
	04_Steady_State_Response.ma
	05_Root_Locus.ma	  
	06_Freq_Response.ma 
	07_State_Space.ma         
	
FILES in directory "For_2.0":
	LaplaceTransform.m     DiracDelta.m	
	SUB-DIRECTORIES in "COSY_PAK":	Common
	FILES in directory "Common":  Support.m

********************* Important ********************	

	The notebook example files(.ma files) will be under the 
"COSY_Notes" directory.  To use the notebooks, move the directory `COSYPAK' to  
a 
directory that  Mathematica can recognize :
	
        /LocalLibrary/Mathematica/Packages     	on a UNIX machine,
        MY_HardDisk:Mathematica:Packages   	on an Apple Macintosh,
        c:\winmath\packages                  	on an IBM PC.

	At the beginning of the "Initialization" cell of each notebook 
in  "COSY_Notes" directory, we list the example about how to make 
Mathematica identify the directory:

	(* Initialization of Path *)

	(* Example For a UNIX machine  (Default) *) 
	(*
	$Path=Join[$Path,
	{"/LocalLibrary/Mathematica/Packages"}];
	*)
	
	(* Example For an Apple Macintosh  *) 
	(*
	$Path=Join[$Path,
	{"MY_HardDisk:Mathematica:Packages"}];
	*)
	
	(* Example For IBM PC 	
	 *)
	(*
	$Path=Join[$Path,	
	 {"c:\winmath\packages"}];	
	*)	

Change the pathname according to your machine by removing the 
Mathematica comment sign `(*' and `)*' before and after `$Path' 
setting.

	This command makes Mathematica recognize the directory

        /LocalLibrary/Mathematica/Packages     	on a UNIX machine
        MY_HardDisk:Mathematica:Packages   	on a Apple Macintosh
        c:\winmath\packages                	on an IBM PC


--> Mathematica 2.0 users
	
	We include the LaplaceTransform package from Mathematica 2.1 in 
the directory For_2.0. Please move all files and directory under For_2.0 
into the Calculus directory under Mathematica Packages directory. 


--> Getting started

       After installation, start Mathematica and open the notebooks in 
the "COSY_Notes" directory. All notebooks load their own packages. 
Navigate in the notebooks and enjoy. IBM users however will have to 
evaluate the notebooks to visualize the graphics.
