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.

Software installed in the lab that can also be used at home:
[Instructions for Windows]
1. Install a GIT client https://git-scm.com/downloads
2. In Matlab run the following lines:
% the next line is long (ends at
\mapi)
!git clone https://github.com/josegaspar999/TecnicoULisboa_MAPI.git
c:\users2\mapi
cd c:\users2\mapi\_init_all
login_z_install
