Adaptive Phase-Aligned Delayed Output Feedback Control Based on Adaptive Frequency Oscillator for Hip Exoskeletons

Traditional delayed output feedback control (DOFC) for hip exoskeletons provides a model-free and computationally efficient approach for gait assistance. However, fixeddelay DOFC is susceptible to phase mismatch under variable cadence conditions. To address this issue, a DOFC framework based on an adaptive frequency os...
