Intelligent control

Objectives

Study of inteligent control techniques, both theoreticaly and applied. Starting by introducing concepts on linear dynamic systems identification and adaptive pole placement control, followed by the use of artifitial neural networks and fuzzy logics as means to approximate nonlinear dynamics. The core of this course is the development of neural and fuzzy controllers.

Teaching method

Theoretical-practical classes and practical laboratory classes.

Evaluation method

The course assessment comprises two components: Lab. work ((TG1.1 + TG1.2 + TG1.3)) + two quizzes.

The CI grade is given by:

NP = (TG1.1 + TG1.2 + TG1.3)/3

Grade Normal=  NP*0.4/3 + (MT 1 + MT 2)*0.3;

Grade Exam=  NP*0.4/3 + Exam*0.6.

Required a minimum attendance of 67% in practical classes and minimum of 9.5 out of 20 in all components.
