Our contributions. environment includes the plant, the reference signal, and the calculation of the Reinforcement Learning (RL) addresses the problem of controlling a dynamical system so as to maximize a notion of reward cumulated over time. This element of reinforcement learning is a clear advantage over incumbent control systems because we can design a non linear reward curve that reflects the business requirements. Reinforcement learning is well-suited to learning the op-timal control for a system with unknown parameters. stream regulation and tracking problems, in which the objective is to follow a reference trajectory. Due to its generality, reinforcement learning is studied in many disciplines, such as game theory, control theory, operations research, information theory, simulation-based optimization, multi-agent systems, swarm intelligence, and statistics.In the operations research and control literature, reinforcement learning is called approximate dynamic programming, or neuro-dynamic programming. However, more sophisticated control is required to operate in unpredictable and harsh environments. policy in a computationally efficient way.

Reinforcement Learning for Control Systems Applications The behavior of a reinforcement learning policy—that is, how the policy observes the environment and generates actions to complete a task in an optimal manner—is similar to the operation of a controller in a control system. The environment represents an urban stormwater system and the agent represents the entity controlling the system. The ability of a control agent to learn relationships between control actions and their effect on the environment while pursuing a goal is a distinct improvement over prespecified models of the environment.
