Abstract

This work considers state dynamics driven by Periodic Autoregressive Moving Average noise, and control of the system over time. Such processes appear frequently in applications involving the environment, such as energy and agriculture. Managing these systems applying forecasts to make decisions that exhibit foresight and risk aversion while maximizing profits is a challenging control problem that can be computationally difficult for standard scenario-based methods. This paper presents a formulation that explicitly enforces time-periodicity of distribution of the state, facilitating the use of periodic stochastic process basis elements as a discretization. By enforcing periodicity explicitly, an ansatz for the solution can be formed that does not require exponential scaling with time. We provide a few examples that can be modeled with this new control formulation.
