Class Automatic Control I

The skills to be developed are as follows:

1. Ability to mathematically model physical systems, whether mechanical (translational and rotational) systems or electrical equipment (eg electric motors).
2. Ability to develop electrical models for physical systems simulation and performance analysis.
3. Ability to analyze behavior of systems (feedback or not) in response to various types of input.

Definitions and basic concepts. Notion of feedback. Open / closed loop systems. Introduction to closed loop control.

Mathematical models of physical systems. Electrical models of systems. Obtaining the mathematical model of translation systems and rotational systems. Mathematical models of electric motors.

Block algebra. Simplification of block diagrams.

Transient and steady state response analysis of 1st and 2nd order systems. Step, impulse and ramp response.

Stability. Routh-Hurwitz stability criterion.

Stationary errors and system types.

Root Locus. Systems design. System compensation.

PID controllers. Tuning.

One third of the classes will be devoted to the presentation of theoretical concepts. In another third of the classes will be presented examples of the application of the theoretical concepts. The remaining third will be laboratory classes where will be given a set of evaluation works that will contribute to the final grade. Most of the work will be done using the Matlab program. The Power Point presented in the classes will be made available to the students, as well as several functions in Matlab to support the laboratory classes.
