Description: Nonlinear dynamics are found in all practical systems. If a detailed model of the behavior of a system is known, it may be possible to design a nonlinear control strategy, which improves the stability and performance of the system. However, although nonlinear control theory is precise, it is often mathematically complicated and deemed hard to implement in a practical system.

An example of a nonlinear system is a power converter connected to a renewable energy source. Power converters are becoming key devices in modern power systems due to the rapid introduction of renewable energy sources. Due to their nonlinear behavior, classical controllers (e.g., PID controllers) are generally not able to provide good performance; and to make matters worse, the nonlinear dynamics will not only degrade the performance of the device itself, but also the stability and reliability of the connected electrical power grid.
The course aims at building a fundamental understanding how to implement nonlinear control methods in a real system (power converters in power system) and demonstrate the aforementioned performance improvement relative to linear control.

Prerequisites: This course is intended for researchers and engineers for control engineers exploring newapplications of control theory in power electronics, and for advanced university students in these fields. General knowledge basic control theory is preferred. Couse exercises will be performed on MATLAB/Simulink.

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 3,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
