Robust n-DOF H∞ feed-forward control of multi-phase converters for electric vehicles

Design and experimental verification of a simplified controller for high‐order converters

“…3,4 In practice, high-end converter systems can be found everywhere, such as automotive control systems, servo motor control systems, industrial production process control systems, and electric vehicles. 5 High-order systems are difficult to represent and control, and the resulting complex design methods cannot usually be used as a practical guide for real-world applications. The transfer function of a highorder system contains a large number of poles and zeros points, and its Bode diagram is more difficult to analyze than a conventional non-minimum phase system.…”

“…However, multiple reactive components (inductors and capacitors) are usually used in modern converter systems, which leads to highly nonlinear converter systems and consequently high‐order models 3,4 . In practice, high‐end converter systems can be found everywhere, such as automotive control systems, servo motor control systems, industrial production process control systems, and electric vehicles 5 . High‐order systems are difficult to represent and control, and the resulting complex design methods cannot usually be used as a practical guide for real‐world applications.…”
