abstract: "A novel method on safety-aware trajectory tracking is presented in this work. The proposed scheme employs Control Barrier Functions (CBFs) along with a latent-space representation over the barrier and its derivatives. While such representations have also been employed in the literature, the innovation of the proposed method lies in formulating a novel tracking problem on the latent space, enabling for the shape of linear class−K functions that are included in the safety condition induced by the control barrier function to be chosen constructively. Additionally, the aforementioned safety condition is modified based on the latent-space tracking through the addition of an extra term. This enables maintaining safety guarantees and is demonstrated to provide decreased tracking errors compared to the nominal control barrier function scheme. Numerical simulations validate the efficacy of the proposed scheme, as well as its ability for online implementation."

abstract: "This paper proposes a sampled-data, measurementrobust, risk-aware control barrier function (RA-CBF) framework for stochastic systems with measurement uncertainty. In this framework, what is available for control design are measurements of the system states, which are subject to unknown noise. First, in order to estimate the system states from these measurements, an offline-trained neural network is employed as a state estimator. Next, to quantify the performance of the state estimator, the state space is discretized, and calibration datasets are sampled from the grid points. Conformal prediction is then implemented, providing the estimation error bound with user-defined probability. In addition, we leverage the estimation error bound into sampleddata robust RA-CBF design, such that the probability that the state of the system enters the unsafe set during a finite time horizon is bounded by a desired threshold. Various case studies demonstrate the effectiveness of the proposed method."
