Model Reference Adaptive Control Scheme for Retuning Method-Based Fractional-Order PID Control with Disturbance Rejection Applied to Closed-Loop Control of a Magnetic Levitation System

Abstract: This study demonstrates the utilization of model reference adaptive control (MRAC) for closed-loop fractional-order PID (FOPID) control of a magnetic levitation (ML) system. Design specifications of ML transportation systems require robust performance in the presence of environmental disturbances. Numerical and experimental results demonstrate that incorporation of MRAC and FOPID control can improve the disturbance rejection control performance of ML systems. The proposed multiloop MRAC–FOPID control structure… Show more

“…Thus, a change in control performance of inner loop can be easily detected by observing model error signal and then this mismatch can be tolerated by contributions of the MIT rule. Multi-loop control architectures have been addressed previously to improve certain weaknesses of conventional PID systems, and related works indicates potentials of multi-loop control structures to improve control performance [28][29][30][31][32]. Majority of these studies aim retuning of PID controller coefficients according to the model mismatch error.…”

“…The topic of multi-loop control involves a wide variety of control systems that employ multi-loop control structures, including cascaded control loops [11,12], multi-input multi-output control systems [13], use of additional control loops for performance improvements [14,15], direct model reference control based on output matching [16,17], direct model reference adaptive control with online controller tuning [5][6][7][8][9][10], model reference adaptive control based on Massachusetts Institute of Technology (MIT) rule [18][19][20][21][22][23], backstepping-based adaptive PID control [24], and hierarchical ML-MR adaptive control [25][26][27][28]. The current study investigates several configurations of hierarchical ML-MR adaptive control structures.…”

“…Hierarchical ML-MR adaptive PID control has been investigated, and certain benefits of this structure related to fault tolerance [25] and disturbance rejection [26] have been discussed. This structure can be easily applied to the existing closed loop PID control systems, thus transforming the PID control systems into model reference adaptive PID control systems.…”

“…Bu yayında önerilen bozucu dışlayıcı kontrol yapısı, gürültülerin denetçi performansı üzerindeki olumsuz etkilerini azaltan bir denetçi tasarımını hedeflemektedir. Günümüze kadar PID denetçilerin bozucu dışlama kapasitesi üzerine çeşitli çalışmalar yapılagelmiş ve birçok öneriler ileri sürülmüştür [5][6][7][8][9][10][11][12][13][14][15]. Kapalı çevrim kontrol sistemlerinde RDR ile bozucu dışlama kapasitesinin belirlenmesi, kontrol sistemlerinin bozucu dışlama performansı açısından önemlidir [5][6][7].…”
