| 1 | Distributed sensor fault diagnosis for a formation system with unknown constant time delays显示文摘In this paper, a distributed velocity sensor fault diagnosis scheme is presented for a formation of a second-order multi-agent system with unknown constant communication time delays. An existing distributed proportion-derivation(DPD) formation control law is adopted and a delay-independent condition is proposed to guarantee the asymptotical formation stability of the formation system based on the Nyquist stability criterion. Then a distributed fault diagnosis scheme is developed. In each agent, a distributed fault detection residual generator(DFDRG) and a bank of distributed fault isolation residual generators(DFIRGs) are designed based on the closed-loop model of the whole system. Each DFIRG is built up on the basis of a reduced-order unknown input observer(UIO) which is robust to the fault of one neighboring agent. According to the robust relationship between DFIRGs and faults, distributed fault isolation can be achieved. Conditions are presented to guarantee that each agent is able to diagnose faults of itself and its neighbors despite the disturbance of time delays. Finally, outdoor experimental results illustrate the effectiveness of the proposed schemes. | Donghua ZHOU Liguo QIN Xiao HE Rui YAN Ruiliang DENG | 2018 | Science China(Information Sciences)2018，61，11： | 5 |
| 2 | Engineered Spindles of Little Molecules Around Electrospun Nanofbers for Biphasic Drug Release显示文摘Biphasic drug release is a popular advanced drug controlled release profle that has been drawing increasing attention from many felds.Electrospun nanofbers and their derivatives can be act as a strong platform for developing biphasic release dosage forms.In this study,a modifed coaxial electrospinning was implemented,in which little molecule solutions that contain a drug ibuprofen(IBU)and polyethylene glycol(PEG)were exploited as a sheath fuid to surround the core solutions composed of polymer ethyl cellulose(EC)and IBU.The prepared nanofber-based structural hybrids,i.e.,engineered spindles-on-astring(SOS)products,were successfully created and subjected to a series of characterizations.Scanning electron microscopy and transmission electron microscopy results showed the engineered SOS structures.IBU and the carriers EC and PEG had good compatibility,as suggested by X-ray difraction and Fourier transform infrared spectroscopy assessments.In vitro dissolution tests verifed that the SOS products were able to provide a typical biphasic release profle,releasing 40%of the loaded IBU within 1 h in an immediate manner in the frst phase,and the rest of the IBU in a sustained manner in the second phase.A combined mechanism of erosion and difusion is proposed for manipulating the IBU molecule release behaviors. | Hua He Mian Wu Jingwen Zhu Yaoyao Yang Ruiliang Ge Deng‑Guang Yu | 2022 | Advanced Fiber Materials2022，4，2： | 0 |
