This paper addresses collective rotating motions of second-order multi-agent systems in three-dimensional space (3D). Two distributed control protocols are proposed and sufficient conditions are derived under which all agents rotate around a common point with a specified formation structure. Simulation results are provided to illustrate the effectiveness of(More)
BACKGROUND Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a clinically heterogeneous disorder characterized by epileptic seizures, psychosis, dyskinesia, consciousness impairments, and autonomic instability. Symptoms are always various. Sometimes it presents in milder or incomplete forms. We report 4 cases of anti-NMDAR encephalitis with(More)
Based on enhanced interpolation DFT, a novel parameter estimation algorithm for the exponential signal is presented. The proposed two-step solution consists of a preprocessing unit which constructs a new signal sequence by continuously cycle shifting sample points and summing up N buffered exponential signal sample sequences, then an interpolation DFT(More)
In this paper, a novel finite-time synchronization framework for complex nonlinear systems is established. In such a framework, the problem of synchronization at any preset time of complex nonlinear systems is solved by using linear continuous state feedback control laws with time-varying gains. The proposed preset time dependent time-varying control laws(More)
