Human-in-the-Loop Control
Control Theory
Human input
Not completely predictable
In certain scenarios, can be somewhat
predicted
Can we develop control algorithms to keep
systems safe while incorporating nominal
human input?
Past Work
Autonomous cars
Semi-autonomous cars
Contributions
Develop a model for the driver using data learned
over time
Apply this model to semi-autonomous cars and
intervention
Illustrate that incorporating human behavior
improves the performance of a semi-autonomous
architecture
