Course Objectives:

 

 

The MAPI course is intended to provide students with the ability to solve automation problems. To this end, methodologies for analysis and synthesis of discrete event systems are studied, in the form of supervisory controllers that are implemented in industrial devices. Training on the following components will be deepened:

 

 

 

Systems analysis for industrial automation.

 

Methodologies for the implementation of solutions in industrial automation.

 

Programmable Logic Controllers (PLCs) Languages.

 

Computer Numerical Control (CNC) machines.

 

Modeling Discrete Event Systems (DESs).

 

Supervision of Industrial Automation Processes.

 

 

 

 

 

Program:

Ch. 1a - Introduction to the course and to the PLCs Programmable Logic Controllers (PLCs) components. PLC internal structure and operation. Input and output interfaces. Interconnection between PLCs.

Ch. 1b - PLCs Programming Languages Ladder diagrams; Structured Text. Description of the components of a typical language. Flow control structures. Development environments. Networking PLCs. Common programming errors.

Ch. 1c - GRAFCET standard. modeling techniques. Development environment. Interpretation of GRAFCET using Ladder. PLCs network security.

Ch. 2 - Discrete Event Systems Discrete Event System Modeling (DESs). Automata, languages. Petri nets: dynamics and modeling. Restricted and extended models. Network subclasses. Petri nets properties. Exercises and solutions.

 

Ch. 3. Stochastic models Stochastic Petri Nets (SPN). Stochastic Queuing Networks (SQN). Slides.

Ch. 4. Stochastic analysis Markov chain modelling of SPN and SQN. Slides.

 

Ch. 5. Control (MDPs in continuous time)

Ch. 6. Supervisors and Fluid models Methodologies for supervision. Synthesis based on invariants. Examples of application. Slides 1 (SCADA), slides 2 (mutual excl.) and slides 3 (generalized).

 

Ch. 7. Case studies (connection to Industry and Services)

Software installed in the lab that can also be used at home:

[Instructions for Windows]
Install an SVN client, e.g. the freeware TortoiseSVN ** including its command line tools **.
A reboot may be required after installing TortoiseSVN.

In
Matlab run the following lines:
% the next line is long (ends at \mapi)
!svn co  --username mapi2122 --password automation svn://svn.isr.tecnico.ulisboa.pt/dccal/projects/lsdc4_mapi c:\users2\mapi
cd c:\users2\mapi\_init_all
login_z_install
login_mapi

% in the future just run login_mapi
