- Be able to design and implement Automation Systems of low to medium complexity

 

Learning outcomes and competences

At the end of the Curricular Unit, the student should:

- Build and Interpret models

- Finite State Machines, Grafcet and Petri Nets

- Implement State Machines in Micro-Controllers and Programmable Logic Controllers

- Use Grafcet/ST to control Automatic Systems of low to medium complexity

- Understand a given "Specifications Contract" that could have been given by a customer

- Design and implement an Event Driven Automatic Control System, for problems of medium complexity

 - Understand the temporal behaviour of signals involved in discrete event systems and associated time restrictions for elementary systems

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Basic algorithmic and programming skills

Program

* Introduction to Automation Systems:

  - Main Application Domains

  - Case Studies

  - Systems types: discrete event vs. continuous time

 

* Methods for analysis and design of Discrete event systems in the scope of Automation Systems

  - State Machines: Notion. Moore and Mealy. Extensions and application examples

  - Grafcet: Fundamental issues (Step, Transition, Condition, Action, Evolution). Study of classic problems: concurrency, synchronization, resource sharing and hierarchy). Advanced Notions (macro-actions and macro-Steps). Synchronous Implementation.

  - Petri Nets: Notion. Differences and modelling power. Introduction to extensions.

 

* Technologies in automated systems:

  - Detectors: fundamental working principals of industrial detectors (sensors)

  - Actuators - electromechanical, pneumatic and hydraulic

  - Microcontrollers and Programmable Logic Controllers (PLCs): Architecture, programming and interfaces

  - Introduction to Real Time problems on elementary systems controlled by PLCs

Teaching methods and learning activities

1. Theoretical classes include active lectures, case studies and exercises

2. Practical Classes are mostly lab work

* Some lectures will include graded work

* At the start of some lab classes that involve dealing with real equipments, the preparation of the students may be evaluated

* A quiz may be presented to the students at the end of some lab classes ("post-class test")

* Automatic grading systems may be used

Eligibility for exams

- General Attendance Rules of FEUP regarding lab classes

- Get grades above minimum in each of the Mid Terms

Calculation formula of final grade

Final Grade (out of 20):

- Lab Component CL (*) : 6

- Written Exam Component CE (*) : 14

- Theoretical Component CT - 2 additional (over 20), non-mandatory related to Theoretical Classes (ex. nano-Testes)

 

(*) Attetntion: if CL excessively above CE (difference above 4), CL will be adjusted so that difference wil be 4

 

CL:

 -  PL part – average of lab work (disregarding worst grade) –each lab work is P_Li and total is N_PL

 - uT part – average of Micro Testes (disregarding worst grade) – each test is u_Ti and total is  N_uT

 

PL = (  ∑(P_Li) - min(P_Li) )  /  ( N_PL - 1 )

uT = (  ∑(u_Ti) - min(u_Ti) )  /  ( N_uT - 1 )

CL = (PL + uT)/2

 

Final grade:

CL2 = min(CL,CE+4)

NF  = min(CL2+CE+CT,20)

 

Obs:

 - A prova de recurso substitui apenas a nota do exame

 - Os trabalhos PL são entregues em grupo

 - Todas as componentes de notas são individuais

Examinations or Special Assignments

* Lab component is mandatory

* Students that have class misses justified still have to turn in lab work for grading

Special assessment (TE, DA, ...)

* Lab component is mandatory

* Students that have class misses justified still have to turn in lab work for grading

Classification improvement

* CE - written exam grade can be improved in 2nd call exam

* CL - only on next ocurrence

Observations

Lab Classes:

* 2 students per bench

* Due to restrictions of equipment, students should NOT exchange classes (keep to your schedule!)

* No class changes (except for really exceptional circumstances decided by the teachers)

* No group changes throughout the semester even within classes (except for really exceptional circumstances decided by the teachers)

* Justifications of missed classes to be turned in digitally to the pratical teacher and to the secretary

 

Theoretical Classes:

* Theoretical classes are repeated and are often but not mandatory aligned

* Ideally, students should keep to same class but it is possible to change Theoretical classes freely

 

Obtaining higher grades:

* Lab grade valid for one additional occurrence;

* It is possible to improve only the grade concerned with written tests (in the following occurrence) -- such students should NOT enrol in practical classes;

* All students should have valid secretary enrolment

 

Dates for the tests:
(To be defined)
