Controlo Industrial

Basic mathematics, applied physics, systems and signals, programming concepts and, optionally, electronics and instrumentation.

1 – Expository method: an explanatory method where facts, concepts, principles, and generalizations are defined and presented by the teacher and discussed with the class, followed by demonstrative examples;

2 – Experimental method: an active method where the student develops knowledge through problem-solving and project development, in group dynamics and individual reflective work.

Particular emphasis is placed on the practical application of theoretical concepts, namely through the use of programmable logic controllers (PLCs) in real or simulated industrial systems, supported by the development of laboratory-based practical assignments.

Upon successful completion of the course, students are expected to be able to:

• Demonstrate an understanding of the fundamental principles of industrial control systems;
• Analyze and design control solutions applied to industrial processes;
• Program and effectively use programmable logic controllers in industrial environments;
• Operate, supervise, and carry out basic maintenance of industrial automated equipment;
• Communicate effectively in technical contexts with professionals in the field of automation and control;
• Initiate professional practice in the field of industrial automation with autonomy and critical judgment.

Regarding assessment, the following methods are planned:

Periodic Assessment: individual practical assignments (75%); an individual written exam (25%);

Final Assessment: an individual practical assignment (50%); an individual written exam (50%).

The selection of the assessment regime shall be made at the beginning of the semester, in strict accordance with the established deadlines and conditions, and shall not, as a rule, be subject to alteration thereafter.
