What is Neuro-Fuzzy Control in Elastic Drive Systems?
Neuro-Fuzzy Control in Elastic Drive Systems applies hybrid neural network and fuzzy logic controllers to manage vibrations and nonlinearities in two-mass drive systems with elastic shafts.
This subtopic focuses on adaptive control for elastic coupling in drives like rolling mills, combining neuro-fuzzy inference for model-free tuning. Key works include sensorless neuro-fuzzy sliding-mode control (Orłowska-Kowalska et al., 2012, 13 citations) and adaptive fuzzy vibration suppression (Qian et al., 2020, 16 citations). Over 10 papers from 2011-2025 address stability and observer integration.
Why It Matters
Neuro-fuzzy control enhances reliability in rolling mills by damping torsional vibrations from elastic shafts, reducing downtime in steel production (Radionov et al., 2021, 18 citations; Gasiyarov et al., 2023, 17 citations). It enables sensorless operation for cost-effective industrial drives (Orłowska-Kowalska et al., 2012, 13 citations). Adaptive tuning handles load variations, improving energy efficiency in variable-speed applications like elevators and robotics (Ali, 2011, 1 citation).
Key Research Challenges
Observer Accuracy in Elastic Torque
Estimating shaft torque in two-mass systems requires robust observers amid nonlinear damping (Kabziński et al., 2021, 18 citations). Digital twins face noise from unmodeled dynamics (Radionov et al., 2021, 18 citations). Multilayer approaches improve estimation but increase computation (Wróbel et al., 2021, 3 citations).
Stability Under Load Variations
Adaptive neuro-fuzzy rules must ensure Lyapunov stability during torque fluctuations (Qian et al., 2020, 16 citations). Sliding-mode integration combats chattering in sensorless setups (Orłowska-Kowalska et al., 2012, 13 citations). Input dead-zones complicate vertical vibration control (Qian et al., 2020, 16 citations).
Low-Cost Hardware Implementation
Deploying neural adaptive controllers on elastic drives demands affordable hardware without performance loss (Malarczyk et al., 2023, 5 citations). Balancing observer complexity with real-time execution remains critical (Gasiyarov et al., 2023, 17 citations). Sensorless speed estimation adds estimation errors (Orłowska-Kowalska et al., 2012, 13 citations).
