QFT Control Toolbox for Matlab (Courses for industry)

Course on Robust Control Engineering and the QFT Control Toolbox
to design quantitative robust control systems

The Quantitative Feedback Theory or QFT provides one of the most practical robust control design methods available for applied projects. This intensive course presents the fundamentals of the QFT robust control methodology and its application to a collection of real-world cases. It follows Prof. Garcia-Sanz's new book Robust Control Engineering: Practical QFT Solutions, CRC Press (2017), and uses the QFT Control Toolbox for Matlab. The course offers:

1.- The fundamentals of the QFT robust control technique for a number of real-world control problems, including plants with large model uncertainty, high-performance specifications, multi-objective cases, nonlinear controller options, and multi-input multi-output plants.

2.- A collection of detailed real-world case studies, including satellites with flexible appendages, multi-megawatt variable-speed wind turbines, wastewater treatment plants, large radio telescopes, DC motors and airplane flight control systems.

3.- The Matlab code of the algorithms and calculations used in the resolution of the main examples presented in the course.

4.- The use of the QFT control toolbox for Matlab, which (1) gives solutions from simple PIDs to more advanced control strategies when necessary, (2) deals with plants with model uncertainty, (3) works with multi-objective performance specifications, and (4) keeps the engineering understanding of the design in the frequency domain.

5.- The material presented in this course has been extensively classroom-tested in undergraduate and graduate courses at universities worldwide, as well as in special control courses for industry. The course has received many teaching awards and excellent evaluations over the years.
- The course can be customized according to the client needs.

This is an ideal course for engineers and researchers interested on the design of reliable control solutions for industrial applications.

Desired prerequisite knowledge:
The course starts where a typical undergraduate control course ends. This means that the audience is familiar with the fundamentals of control, including Laplace transforms, Bode diagrams, root locus, stability, PID controllers and elementary state-space theory.

Expected learning outcomes:
This course offers practical QFT methodologies to design reliable control systems, bridging the gap between successfully tested theory and real-world control systems implementation.
