Simplified Fuzzy Logic Controller and Its Application as a Power System Stabilizer
Bibliographic record
Abstract
A simplified fuzzy logic controller (SFLC) with a significantly reduced set of fuzzy rules, small number of tuning parameters and simple control algorithm and structure is presented. The SFLC is derived from a two-dimensional and symmetrical rule table commonly used in fuzzy control applications. In the phase-plane, the required control action magnitude is proportional to the distance from the state of the system to the switching line (defined by the desired zero consequence). Based on the SFLC, a simplified power system stabilizer (SFLPSS) is designed and applied to a single machine-infinite bus system. Simulation studies are carried out to show that the proposed SFLPSS, with a considerably reduced rule base, is able to provide the same response as a fuzzy controller with the original set of fuzzy rules. The results also show the effectiveness of the proposed PSS in damping power system oscillations, as compared to a conventional PSS.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
