Within the last two decades, state-space control methods have become the state-of-the-art for power electronics applications. Their superior dynamic behavior over Proportional Integrator (PI) based schemes makes them the method of choice when it comes to fast and accurate converter control, while still retaining a relatively low computational complexity. Owing to a constant increase in harmonics and disturbance behavior requirements, state-space controller design nowadays already belongs to the tool set of many development teams.
This tutorial is specifically designed for engineers and scientists who want to build up or improve their skills in power electronics control. It provides structured guidelines for state-feedback implementation of current or voltage tracking issues, exposing pitfalls and outlining strategies to avoid them.
The first aim is to convey an intuitive understanding of linear ordinary differential equations, eigenvalues, eigenvectors and their connection to stability, accompanied by representative examples from power electronics. Furthermore, accurate modelling and simulation strategies of continuous and discrete systems are discussed.
The second aim is to enable the participants to design robust state feedback controllers for typical applications. This includes tailored solutions such as prefilter, feedforward and integral action implementation.
To give an extensive hands-on experience, a significant part of the tutorial will consist of assisted exercises.
