Robust Control Barrier and Control Lyapunov Functions with Fixed-Time Convergence Guarantees [PDF]
American Control Conference, 2021 This paper studies control synthesis for a general class of nonlinear, control-affine dynamical systems under additive disturbances and state-estimation errors. We enforce forward invariance of static and dynamic safe sets and convergence to a given goal

Dynamic Consensus With Prescribed Convergence Time for Multileader Formation Tracking [PDF]
IEEE Control Systems Letters, 2022 This letter addresses the problem of distributed formation tracking for a group of follower holonomic mobile robots around a reference signal. The reference signal is comprised of the geometric center of the positions of multiple leaders.

Convergence Time Optimization for Federated Learning Over Wireless Networks [PDF]
IEEE Transactions on Wireless Communications, 2020 In this paper, the convergence time of federated learning (FL), when deployed over a realistic wireless network, is studied. In particular, a wireless network is considered in which wireless users transmit their local FL models (trained using their ...

Prescribed convergence time control of spacecraft attitude dynamics with parametric uncertainty
Nonlinear dynamics, 2023 The prescribed convergence time control issue of spacecraft with parametric uncertainty in inertia and disturbance is investigated. An adaptive sliding mode control solution is given. As a stepping stone, a new practical predefined-time stability theorem

Fast Convergence Time Synchronization in Wireless Sensor Networks Based on Average Consensus [PDF]
IEEE Transactions on Industrial Informatics, 2020 Average consensus theory is intensely popular for building time synchronization in wireless sensor network (WSN). However, the average consensus-based time synchronization algorithm is based on the iteration that poses challenges for efficiency, as they ...

Parameter Identification With Finite-Convergence Time Alertness Preservation [PDF]
IEEE Control Systems Letters, 2020 In this letter note we present two new parameter identifiers whose estimates converge in finite time under weak interval excitation assumptions. The main novelty is that, in contrast with other finite-convergence time (FCT) estimators, our schemes ...

Bearing-Only Formation Control With Prespecified Convergence Time
IEEE Transactions on Cybernetics, 2020 This article considers the bearing-only formation control problem, where the control of each agent only relies on relative bearings of their neighbors. A new control law is proposed to achieve target formations in finite time. Different from the existing

Loosely-Stabilizing Leader Election with Polylogarithmic Convergence Time
International Conference on Principles of Distributed Systems, 2020 A loosely-stabilizing leader election protocol with polylogarithmic convergence time in the population protocol model is presented in this paper. In the population protocol model, which is a common abstract model of mobile sensor networks, it is known to
