    Observability and Observed-Based Control for a Class of Output Modular Systems With Application to Modular Multilevel Power Converters
    (2024) Gallegos Veliz, Javier Andrés; Rubio Barros, Francisco Javier; Pereda Torres, Javier; Núñez, Felipe
    Modularity, understood as the property that allows a complex system to be decomposed into well-defined compartments, is a distinctive element in modern engineering systems. Modularity increases scalability, facilitates mass production, and simplifies maintenance. Nonetheless, modular systems may exhibit complex dynamics, and the establishment of their structural properties can be challenging. In this brief, observability and observer-based control for a class of modular nonlinear systems are analyzed, with particular focus on the modular multilevel power converter. Analytical conditions to verify observability are given, a separation principle that enables observer-based control is formulated, and an experimental validation on a pilot-scale converter is conducted to corroborate the analytical findings
