Adaptive Armature Resistance Control of Virtual Synchronous Generators to Improve Power System Transient Stability
Energies, 2020Co-Authors: Daniel Carletti, Arthur E. A. Amorim, Thiago Silva Amorim, Domingos Sávio Lyrio Simonetti, Jussara Farias Fardin, Lucas Frizera EncarnaçãoAbstract:The growing number of renewable energy plants connected to the power system through static converters have been pushing the development of new strategies to ensure transient stability of these systems. The virtual synchronous generator (VSG) emerged as a way to contribute to the system stabilization by emulating the behavior of traditional synchronous machines in the power converters operation. This paper proposes a modification in the VSG implementation to improve its contribution to the power system transient stability. The proposal is based on the virtualization of the resistive superconducting fault current limiters’ (SFCL) behavior through an adaptive control that performs the VSG Armature Resistance change in short-circuit situations. A theoretical analysis of the problem is done based on the equal-area criterion, simulation results are obtained using PSCAD, and experimental results are obtained in a Hardware-In-the-Loop (HIL) test bench to corroborate the proposal. Results show an increase in the system transient stability margin, with an increase in the fault critical clearing time (CCT) for all virtual Resistance values added by the adaptive control to the VSG operation during the short-circuit.

Adaptive control of automotive electronic throttle
Control Engineering Practice, 2006Co-Authors: Danijel Pavković, Joško Deur, Martin Jansz, Nedjeljko PerićAbstract:An electronic throttle is a DC servo drive which positions the throttle plate, thus providing drive-by-wire control of engine torque. This paper presents an electronic throttle control strategy consisting of a PID controller, and nonlinear friction and limp-home compensators. The emphasis is on the development of an adaptive control strategy, which is aimed to enhance the control strategy robustness with respect to process parameter variations, caused by production deviations, variations of external conditions, and aging. The adaptive strategy consists of auto-tuning and self-tuning algorithms. The auto-tuner provides automatic tuning of the control strategy parameters during vehicle assembly, or uses specific drive modes during normal use (e.g. each time the engine is turned off). The self-tuning algorithms are based on the permanent, on-line estimation of those process parameters which can vary within a single engine run (e.g. the DC motor Armature Resistance). The presented adaptive control strategy has been verified experimentally.

Self-tuning control of an electronic throttle
Proceedings of 2003 IEEE Conference on Control Applications 2003. CCA 2003., 1Co-Authors: Danijel Pavković, Joško Deur, Martin Jansz, Nedjeljko PerićAbstract:A self-tuning strategy for an electronic throttle servo-system is proposed in order to account for the variations of DC motor Armature Resistance, battery voltage, and limp-home position. Different self-tuning algorithms have been derived depending on the availability of Armature current sensor and control strategy auto-tuning procedure. The presented self-tuning algorithm has been experimentally verified on an experimental setup of electronic throttle control system. For the purpose of experimental verification, a real-time simulator of process parameters variations has been developed.
