Goals

This represents an advanced course of Automatic Nonlinear Control and Supervision techniques for complex systems, and it studies advanced elements of a control and fault diagnosis system from the dynamic point of view, by considering nonlinear dynamic processes from their input-state-output and input-output points of view. This course thus aims at presenting those control and supervision methodologies currently required and expected by modern industries and practical application activities. The main goal of the course consists of providing advanced topics and tools for the study, supervision, fault diagnosis and control of complex dynamic systems, as well as their interconnections under proper design constrains imposed by cost, speed, computational cost, robustness, reliability, sustainability, and power consumption.

Examination Method

If the rules of the PhD course of the candidate require an official exam, a project will be assigned with the implementation and the analysis of the most interesting fault diagnosis strategy of interest for the candidate. It will aim at understanding if the student has acquired the skills of the course.
If the rules of the PhD course of the candidate do not require an official exam, an attendance certificate will be issued to the student, apon request.
