In this paper, we consider the problem of reference tracking in uncertain nonlinear systems. A neural State-Space Model (NSSM) is used to approximate the nonlinear system, where a deep encoder network learns the nonlinearity from data, and a state-space component captures the temporal relationship. This transforms the nonlinear system into a linear system in a latent space, enabling the application of model predictive control (MPC) to determine effective control actions. Our objective is to design the optimal controller using limited data from the target system (the system of interest). To this end, we employ an implicit model-agnostic meta-learning (iMAML) framework that leverages information from source systems (systems that share similarities with the target system) to expedite training in the target system and enhance its control performance. The framework consists of two phases: the (offine) meta-training phase learns an aggregated NSSM using data from source systems, and the (online) meta-inference phase quickly adapts this aggregated model to the target system using only a few data points and few online training iterations, based on local loss function gradients. The iMAML algorithm exploits the implicit function theorem to exactly compute the gradient during training, without relying on the entire optimization path. By focusing solely on the optimal solution, rather than the path, we can meta-train with less storage complexity and fewer approximations than other contemporary meta-learning algorithms. We demonstrate through numerical examples that our proposed method can yield accurate predictive models by adaptation, resulting in a downstream MPC that outperforms several baselines.

In the paper, the results of the predesigning a RoF-Based Millimeter-Wave Access Sub-Network in a Megapolis 5G Cellular Communication system are presented and discussed. In order to put the study in a practical direction, the capital of the Russian Federation, the city of Moscow, was chosen as a realistic object under investigation. On its territory, one of the largest in terms of area and population, the Western administrative district, was selected, and within it, the municipal district of Ramenki, in which a fiber-wireless-configured network with wireless communication in the band of 37.0-43.5 GHz was predesigned.
