Fault-Tolerant Control for Quadrotor Based on Fixed-Time ESO
Mathematics, 2022 Focusing on the actuator fault of the quadrotor unmanned aerial vehicle (QUAV), an active fault-tolerant control scheme based on fixed-time linear active disturbance rejection control is proposed.

Thermodynamic Length, Time, Speed and Optimum Path to Minimize Entropy Production
, 1995 In addition to the Riemannian metricization of the thermodynamic state space, local relaxation times offer a natural time scale, too. Generalizing existing proposals, we relate {\it thermodynamic} time scale to the standard kinetic coefficients of ...

IEEE Access, 2021 In this research, a new robust control method is developed, which achieves a fixed-time convergence, robust stabilization, and high accuracy for trajectory tracking control of uncertain magnetic levitation systems. A hybrid controller is a combination of

Dissipative Two-Mode Tavis-Cummings Model with Time-Delayed Feedback Control
, 2015 We investigate the dynamics of a two-mode laser system by extending the two-mode Tavis-Cummings model with dissipative channels and incoherent pumping and by applying the mean-field approximation in the thermodynamic limit.

Convergence of the empirical spectral measure of unitary Brownian motion [PDF]
, 2018 Let $\{U^N_t\}_{t\ge 0}$ be a standard Brownian motion on $\mathbb{U}(N)$. For fixed $N\in\mathbb{N}$ and $t>0$, we give explicit bounds on the $L_1$-Wasserstein distance of the empirical spectral measure of $U^N_t$ to both the ensemble-averaged spectral

A Parametric Multi-Convex Splitting Technique with Application to Real-Time NMPC [PDF]
, 2014 A novel splitting scheme to solve parametric multiconvex programs is presented. It consists of a fixed number of proximal alternating minimisations and a dual update per time step, which makes it attractive in a real-time Nonlinear Model Predictive ...

Geometric control condition for the wave equation with a time-dependent observation domain [PDF]
, 2016 We characterize the observability property (and, by duality, the controllability and the stabilization) of the wave equation on a Riemannian manifold $\Omega,$ with or without boundary, where the observation (or control) domain is time-varying.
