Super-Twisting Gain Adjustment for a Direct Current Motor

https://doi.org/10.58571/CNCA.AMCA.2025.019

Resumen: This paper proposes a gain design for Super-Twisting control applied to a Direct Current (DC) motor. The describing function approach is employed to predict the chattering characteristics—specifically, the amplitude and frequency of self-excited oscillations—arising from parasitic dynamics modeled as a transport delay. Based on this analysis, a gain tuning strategy is developed to minimize the amplitude of the dominant harmonic. The effectiveness of the proposed methodology is validated through experimental results on the DC motor.
