Optimal modulation, such as optimized pulse patterns (OPPs), can produce very low harmonic distortions. However, due to inherent difficulties, OPPs cannot be easily utilized in a closed-loop control setting with conventional control techniques. This lecture discusses how optimal control can enable the design of high-bandwidth controllers that can fully harvest the advantages of OPPs. Moreover, aspects that relate to the control concept, formulation, and real-time implementation are analyzed. The superior steady-state and dynamic performance

of the presented control algorithms is demonstrated with two different case studies: low- and medium-voltage variable-speed drive systems.
