제목 Optimal control for aftertreatment system of vehicle using digital twin and reinforcement learning
초록 Diesel vehicles cause environmental problems including NOx emission. To reduce NOx, various catalysts have been developed, and operation strategies have been proposed to use catalytic reactors efficiently. This study constructs a digital twin for a selective catalytic reactor which is widely used, and we design optimal control policies using a reinforcement learning method with the digital twin. For the automotive aftertreatment system with limited information to be measured, more virtual data can be obtained using a digital twin. In addition, optimal control policies reflecting the characteristics of the system are proposed using the reinforcement learning method based on the digital twin.
