Robust Impedance Control Of A Four Degree Of Freedom Exercise Robot, Santino Joseph Bianco Jan 2019

Robust Impedance Control Of A Four Degree Of Freedom Exercise Robot, Santino Joseph Bianco

ETD Archive

The CSU 4OptimX exercise robot provides a platform for future research into advanced exercise and rehabilitation. The robot and its control system will autonomously modify reference trajectories and impedances on the basis of an optimization criterion and physiological feedback. To achieve this goal, a robust impedance control system with trajectory tracking must be implemented as the foundational control scheme. Two control laws will be compared, sliding mode and H-infinity control. The above robust control laws are combined with underlying impedance control laws to overcome uncertain plant model parameters and disturbance anomalies affecting the input signal. The sliding mode control law …
