Qft Controller Of Switched Reluctance Motor



Authors : Tahour Ahmed . Aissaoui Abdel Ghani .

Abstract

This study presents the implementation of Quantitative Feedback Theory (QFT) for the robust speed control of a variable reluctance motor (SRM). Introduced by Isaac Horowitz, QFT is a robust control approach formulated in the frequency domain, allowing for the systematic handling of parametric uncertainties and external disturbances while respecting predefined performance constraints. Unlike classical control strategies, which are generally based on a nominal model of the system, QFT explicitly considers a set of uncertainties describing the possible variations of the model. This consideration guarantees both robust stability and performance maintenance throughout the uncertainty range. Applied to SRM control, the proposed method significantly improves the dynamic response, disturbance rejection capability, and system stability margins. Simulation results and experimental tests confirm that the QFT controller provides more precise speed regulation, faster transient response and increased robustness to parametric variations and load disturbances, compared to conventional proportional-integral (PI) control.
