Specific course objectives

The course aims at providing a theoretical and practical vision of a digital acquisition system suitable to measure environmental physical parameters like temperature, pressure, acceleration and so on while controlling common moving and actuation systems.
The students will become able to do so by recovering most concepts learned in the courses of Physics, Electronics and Computer Architecture.
Then, main control algorithms are considered both from the theoretical and its digital implementation point of view.
Finally, practical industrial processes are depicted into which the students will achieve the capability of conceiving and carrying out a complete process control systems, starting from the acquisition of suitable process variables.

Course programme

Introduction to the course and to the electronic measurements chains.

Transducers
General features of transducers. Transducers for the measurements of the linear and angular position and velocity, of the acceleration, of the pressure, of the temperature, of flow, of the level and of the acidity.

Conditioning electronic circuits
Voltage-current and current-voltage, charge-voltage and frequency-voltage converters. Bridge circuits. Operational amplifiers in measurements chains: not linear amplification with diodes and AC-DC converters single and double wave. Synchronous rectifiers. Instrumentation amplifier and common mode rejection ratio. The sampling problem: Shannon's theorem. Electronic circuits for ultrasound transducers.

Actuators
SCR (Silicon Controlled Rectifiers), Triac and UJT Transistors. Step motors and Direct Current motors.

Control algorithms
Proportional, Proportional-Integral, Proportional-Integral-Derivative techinques. On-Off algorithm. Feedforward. Cascade control. Bode diagrams. Numerical implementation techniques. Optimal controllers.

Industrial processes
Typical and real industrial examples into which students will learn how to design the whole control chain consisting of acquisition system with amplifying and digital conversion to the microprocessor, together with the choice of a proper control algorithm to assure the system stability.

Testing and exams

Two kinds of exams have been conceived:

Tests during the course:
The following rules are set: 1. the first trail deals with topics faced in the first part of the course that students are requested to explain and analyse in detail; 2. the second trial deals with topics that are faced in the time from the first trial and the end of the lessons; again students are requested to explain and analyse them in detail. The access to this trial is allowed if the first one has been passed.

Full exams:
In this case, the exam concerns the whole course program.
