摘要：In this article, the fixed-time attitude tracking control for spacecraft is investigated. By introducing dynamic powers, a novel terminal sliding function and a novel nonsingular practical fixed-time tracking control law are developed. In particular, the dynamic powers in the proposed sliding function is constructed via the modified Rodrigues parameters (MRPs) and control law is designed by using the sliding mode variable. An important feature of the proposed dynamic powers-based sliding funct...

摘要：In binary decision making under the linear threshold model, each individual has a time-invariant threshold and is either a conformist, who tends to adopt an action if the population proportion of adopters exceeds their threshold, or a nonconformist, who tends to adopt if it falls short. The resulting decision-making dynamics can be predicted and controlled, provided that the thresholds are known. In practice, however, the thresholds are unknown and often only the evolution of the total number ...

摘要：This article investigates the design problem of periodic event-triggered quantized control (PETQC) for general nonlinear networked control systems (NCSs) with multiple communication channels between the plant and the controller. The transmission of information over these channels is asynchronous, and the transmission instants are determined by a local dynamic event-triggering mechanism (ETM). In each channel, continuous signals are sampled and quantized with a dynamic quantizer (DQ) before bei...
