Active Disturbance Rejection Control in Two-Mass Systems
Research Guide
What is Active Disturbance Rejection Control in Two-Mass Systems?
Active Disturbance Rejection Control (ADRC) in two-mass systems applies extended state observers and nonlinear control laws to suppress torsional vibrations and improve speed tracking in elastic drive systems with uncertainties.
ADRC treats model uncertainties and disturbances as a total disturbance estimated by an extended state observer (ESO). Researchers apply ADRC to two-mass systems modeling motor-load connections via elastic shafts in servo drives. Over 20 papers since 2014 explore ESO designs and control synthesis for robustness (Wei et al., 2014; Radionov et al., 2021).
Why It Matters
ADRC enhances robustness in industrial servo drives where elastic couplings cause vibrations, outperforming PID controllers under parameter variations (Yuan et al., 2020). In rolling mills and electric vehicles, two-mass ADRC reduces torsional oscillations for precise speed control (Radionov et al., 2021; Hu et al., 2019). Metaheuristic optimization of ADRC parameters improves high-speed drive performance (Malarczyk et al., 2024).
Key Research Challenges
Torsional Vibration Suppression
Elastic shafts in two-mass systems amplify oscillations under load torque disturbances. ESO must estimate unmodeled dynamics without high-gain amplification (Radionov et al., 2021). Multilayer observers reduce estimation errors in flexible drives (Wróbel et al., 2021).
Parameter Uncertainty Handling
Stiffness and damping variations degrade performance in uncertain two-mass models. Robust control structures like pattern-search tuned PI require disturbance rejection (Wróbel et al., 2023). Fuzzy adaptive controllers address nonlinear coupling effects (Derugo et al., 2022).
Observer Design Stability
Fractional-order ESOs for time-series disturbances need nonlinear weighting for stability. Virtual signal estimation via neural models improves state feedback in elastic systems (Stanisławski et al., 2023). Multilayer Luenberger observers enhance convergence (Wróbel et al., 2021).
