    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

    The examination is divided into 2 phases that will take place in the same day:
  • A project realised in Matlab and Simulink regarding the design and the simulation of a simple supervision scheme for a nonlinear system by using the Matlab and Simulink environments, which aims at understanding if the student has acquired the skills of the course. The time allowed for this test is about 1 hours.
  • One test (open answers and multiple choice questions) based on all the topics tackled in the class or on the basic concepts of the course, with the aim of evaluating how deeply the student has learnt the subject and how he is able to understand the topics analysed. The time allowed for this test is about 0.5 hour.
