Systems Control Project

The aim is to apply the principles and methods studied in class to real systems. Student engineers complete 5 practical assignments on the following topics.

1. Control of a pneumatic system using a TSX 47 PLC (moving a metal part on a bench using pneumatic cylinders and a conveyor belt)
2. Elevator control by TSX 47 PLC (TSX 47 PLC and elevator model)
3. Implementation of an assembly line (FESTO FEC 640/660 PLC: programming the distribution or assembly module)
4. Closed-loop PID control of an electromechanical system (speed-controlled DC motor)
5. Closed-loop PID control of a time-delay system (temperature-controlled thermal enclosure)

A first objective is to put into practice the concepts and tools seen in the Systems Control course taught earlier in the semester.

A second objective is to introduce students to GRAFCET modeling and the Ladder contact language. The PLCs will be programmed using AUTOMGEN and FST 4.21. 

Skills developed through this module :

• Use mathematical and physical tools in an embedded systems engineering context - level 2

Mathematical prerequisites

• Taylor series development to order 1
• Handling complex numbers (modulus, argument)
• Laplace transform and its properties

Semester 6 automatic prerequisites :

• Frequency representation of linear systems (Bode, Nichols and Nyquist diagrams)
• Handling transfer functions (sums, products, calculation of gain or argument)
• Handling block diagrams

Prerequisites for the Systems Control course :

• Understand the advantages and disadvantages of each elementary control action P, I, D
• Synthesize simple feedback controllers: P, PI, PD(F), PID(F)
• Analyze the stability and performance of a control law

Available on Moodle :
