Modeling and Testing of a Series Elastic Actuator with Controllable Damping

Iyer, Sidharth Suresh 11 January 2012 (has links)
Compliant Actuators are much safer than traditional stiff joint actuators, but at the cost of high overshoot, positional accuracy, and speed. A damper that varies its damping torque during motion is introduced to alleviate these downsides. The equations of motion for the system are derived and simulated. The simulations demonstrated a decrease in the overshoot and ringing time. A physical proof of concept was manufactured and tested. The results from the physical model were inconclusive due to a fault in the physical model. A more accurate physical test model is proposed, and is simulated.
