Journal ArticleDOI
Bifurcations and Hopf Degeneracies in Nonlinear Feedback Systems with Time Delay
TL;DR: In this article, an application of the well-developed frequency-domain approach to detect oscillations in nonlinear feedback systems with time delay is presented, which depends on an early proof of the Hopf bifurcation theorem known as the Graphical Hopf Theorem (GHT).
Journal ArticleDOI
High-Performance Control of a DC–DC Z-Source Converter Used for an Excitation Field Driver
TL;DR: In this article, the authors proposed a multiloop control law for the Z-source converter, which can achieve the desired voltage reference swing and high-performance tracking, and compared the dominant losses of the buck topology, typically used in FESS, and the Zsource converter.
Journal ArticleDOI
High-performance control of a three-phase voltage-source converter including feedforward compensation of the estimated load current
TL;DR: In this article, a nonlinear feedback controller based on feedback linearization plus a feedforward compensation of the estimated load current is proposed to improve the performance of the whole system and to diminish the capacitor size.
Journal ArticleDOI
Predictive functional control based on fuzzy model: magnetic suspension system case study
TL;DR: The Takagi–Sugeno fuzzy model of stabilised system was obtained using fuzzy identification and improved quality and robustness performance compared to PID, and proved to be ideal solution for high sampling frequency systems.
Journal ArticleDOI
High-performance sensorless nonlinear power control of a flywheel energy storage system
TL;DR: In this article, a high performance model-based power flow control law is developed using the feedback linearization methodology, which is based on the voltage space vector reference frame machine model.
