Robust damping controller design for a static compensator

A QPSO based Damping Controller for STATCOM

“…The performance of such controllers can further be improved by adaptively updating their parameters. Although using the robust control methods [5,6], the uncertainties are directly introduced to the synthesis, but due to the size of large power systems the order of resulting controller will be very large in general, which is not feasible because of the computational economical difficulties in practical implementing.…”

Periodic output feedback technique based design of STATCOM damping controller

“…(b) Linear system theory based techniques: In this category, combined state and output feedback [9], two state multimodal LMI approach based output feedback technique [10], robust control techniques [11,12], H 2 norm based approach [13] have been reported in the literature. (c) Non-linear control techniques: Strategies such as direct feedback linearization [14], variable structure control [15], cascaded controller architecture based multivariable nonlinear control strategy [16] have been suggested in the literature.…”

Static Synchronous Compensator Damping Controller Design Using Fast Output Sampling Feedback Technique

“…The developed control strategy has been validated on the two-area four-machine system using only a simplified second-order generator model. Several linear control techniques, such as combined state and output feedback [9], two-state multi-modal linear matrix inequality (LMI) approach based output feedback technique [10], robust control techniques [11,12], H 2 -norm-based approach [13], have also been reported in the literature. While a single-machine infinite-bus (SMIB) system for the validation of the developed control strategies was used in [9,11], a two-area four-machine system has been adopted in [10,12,13] for testing the performance of the proposed control schemes.…”
