A Direct Collocation method for optimization of EMG-driven wrist muscle musculoskeletal model

ICRA 2021poster

EMG-driven musculoskeletal model has been broadly used to detect human intention in rehabilitation robots. This approach computes muscle-tendon force and translates it to the joint kinematics. However, the muscle-tendon parameters of the musculoskeletal model are difficult to measure in vivo and var…

Robust Iterative Learning Control for Pneumatic Muscle with State Constraint and Model Uncertainty

ICRA 2021poster

In this paper, we propose a novel iterative learning control (ILC) scheme for precise state tracking of pneumatic muscle (PM) actuators. Two critical issues are considered in our scheme: 1) state constraints on PM position and velocity; 2) uncertainties of the PM model. Based on the three-element fo…
