Feedback systems

Presentation

Programme (detailed contents):

The course presents the models for linear time-invariant systems, in particular the differential equation and the transfer function. The main methods for analysis of linear systems are then studied (frequency and time responses) and the concepts of open loop and closed loop stability introduced. After defining the main indicators in terms of transient and steady-state behaviours, the design of lead and lag control laws are developed. The PID controller with the main methods of design are then presented

No particular difficulty

Objectives

 

At the end of this module, the student will have understood and be able to explain (main concepts):

The design of closed-loop control laws for linear time-invariant systems described by their transfer function

 

The student will be able to:

To design closed-loop control laws based on specifications of

steady state behaviour (precision) and on transient behaviour (settling time)

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
