This article investigates an asynchronous adaptive fault-tolerant control problem for Markov jump systems (MJSs) with actuator\nfailures and absolutely unknown nonlinear disturbances...............................
Integrated and intelligent in situ observations are important for the remote sensing\nmonitoring of dynamic water environments. To meet the field investigation requirements of ocean\ncolor remote sensing, we developed a water color remote sensing-oriented unmanned surface vehicle\n(WC-USV), which consisted of an unmanned surface vehicle platform with ground control station,\ndata acquisition, and transmission modules..........................
This paper investigates energy efficiency and dynamic behavior through simulation and \nexperiments of a compact electro-hydrostatic actuator system (EHA) consisting of an electric motor, \nexternal gear pump/motors, hydraulic accumulator, and differential cylinder. Tests were performed \nin a stand-alone crane in order to validate the mathematical model..................
In the present study, the chaotic response of the nonlinear magnetostrictive actuator (GMA) vibration system is investigated. The\nmathematical model of the nonlinear GMA vibration system is established according to J-A hysteresis nonlinear model, quadratic\ndomain rotation model, Newtonâ??s third law, and principle of GMA structural dynamics by analyzing the working principle of\nGMA...........................
The demand for multi-functional soft actuators with simple fabrication and fast response to\nmultiple stimuli is increasing in the field of smart devices. However, for existing actuators that respond\nto a single stimulus, it is difficult to meet the requirements of application diversity. Herein, a type of\nmulti-stimulus responsive soft actuator based on the Nafion-Polypropylene-polydimethylsiloxane\n(PDMS)/Graphite multilayer membranes is proposed...........................
