Automation, robotics, sensors - 2019 Revised

Application of the combination of control laws to a study case: aircraft control

OBJECTIVE :

This course is intended for engineers who want to review their knowledge of system control and to apply it to a concrete case study by fully integrating the use of the latest Matlab tools available. The chosen application is the design of a civil aircraft autopilot. The flight area studied will correspond to the complete landing phase of the aircraft (approach and rounding until touchdown). The combination of techniques implemented will cover a broad spectrum:

  • Conventional control: successive closure of loops, location of roots, placement of terminals
  • Modal control: placement of eigenvalues and eigenvectors
  • LQ/LQG control: minimization of an "energy" criterion relating to both the system states and the controls
  • Infinite H control: minimization of a standard on some (frequency-weighted) transfers of the closed loop.

A significant part of the course will focus on practical work with Matlab/Simulink, thereby enabling learners to focus on the adjustment of the various control techniques and on understanding compromises beyond the theoretical level. The laws developed will be implemented and tested on a 3-axis non-linear Simulink model representative of the behavior of a civil aircraft in the landing phase.

COURSE DURATION AND TIMETABLE :

The course lasts 3 days (18 hours).

It combines lectures and numerous practical sessions at a workstation.

GENERAL APPROACH :

Emphasis will be given to the practical aspects of adjustment and implementation, rather than on the theoretical aspects, focusing as much as possible on the physical understanding of the phenomena.

PREREQUISITE :

Course level: Expert

Basic automation knowledge is required: frequency and modal control.
