Deep Reinforcement Learning Based Networked Control with Network Delays for Signal Temporal Logic Specifications

no code implementations3 Aug 2021 Junya Ikemoto, Toshimitsu Ushio

We apply deep reinforcement learning (DRL) to design of a networked controller with network delays to complete a temporal control task that is described by a signal temporal logic (STL) formula.

Continuous Deep Q-Learning with Simulator for Stabilization of Uncertain Discrete-Time Systems

1 code implementation13 Jan 2021 Junya Ikemoto, Toshimitsu Ushio

If we know a mathematical model of a real system, a simulator is useful because it predicates behaviors of the real system using the mathematical model with a given system parameter vector.

Networked Control of Nonlinear Systems under Partial Observation Using Continuous Deep Q-Learning

no code implementations28 Aug 2019 Junya Ikemoto, Toshimitsu Ushio

In this paper, we propose a design of a model-free networked controller for a nonlinear plant whose mathematical model is unknown.
