LCSR Seminar: Brent Gillespie
Description
Brent Gillespie, a professor of mechanical engineering and robotics at the University of Michigan, will give a talk titled "Predicting Human Behavior in Predictable Environments Using the Internal Model Principle" for the Laboratory for Computational Sensing and Robotics.
Abstract:
All models are wrong, and too many are directed inward. The Internal Model Principle of control engineering directs our attention (and modeling proficiency) to what makes the world around us patterned and predictable. It says that driving a model of that patterned or predictable behavior in a feedback loop is the only way to achieve perfect tracking or disturbance rejection. In the spirit of "some models are useful", I will present a control system model of humans tracking moving targets on a screen using a mouse and cursor. Simple analyses reveal this controller's robustness to visual blanking and experiments (even experiments conducted remotely during the pandemic) provide ample support. Extensions that combine feedforward and feedback control complete the picture and complement existing literature in human motor behavior, most of which is focused on modeling the system under control rather than the environment.
