A fault diagnosis and fault-tolerant control approach is proposed which is based on extended state observer for systems with random disturbance and incipient actuator faults. Firstly, random disturbance and incipient fault are put in the extended state of ESO, thus the incipient fault can be diagnosed without using the residual. Then, the optimal fault-tolerant and dynamic self-repairing control can be achieved by the estimated values of random disturbance and incipient faults. Finally, Simulation results demonstrate the effectiveness and reliability of the proposed approach.

Optimal Design of 850nm 2 × 2 Multimode Interference polymer Waveguide Coupler by Imprint Technique

Photonic Sensors 2016年第3期6卷 234-242页

A 2 × 2 optical waveguide coupler at 850 nm based on the multimode interference （MMI） structure with the polysilsesquioxanes liquid series （PSQ-Ls） polymer material and the imprint technique is presented. The influence of the structural parameters, such as the single mode condition, the waveguide spacing of input/output ports, and the width and length of the multimode waveguide, on the optical splitting performance including the excess loss and the uniformity is simulated by the beam propagation method. By inserting a taper section of isosceles trapezoid between the single mode and multimode waveguides, the optimized structural parameters for low excess loss and high uniformity are obtained with the excess loss of -0.040 dB and the uniformity of-0.007 dB. The effect of the structure deviations induced during the imprint process on the optical splitting performance at different residual layer thicknesses is also investigated. The analysis results provide useful instructions for the waveguide device fabrication.

Moisture Absorption and Mechanical Properties of Chemically Modified Linen/Polypropylene Composites

引用

Chemical Research in Chinese Universities 2017年第6期33卷 1000-1006页

作者： HU Qiuxue LI Li YAN Wenling ZHAO Qi ZHANG Niaona ZHANG Yumei DONG Jinbiao LIU Baijun HU Wei College of Chemical Engineering Changchun University of Technology Changchun 130012 P. R. China School of Life Science and Technology Harbin Institute of Technology Harbin 150080 P. R. China College of chemistry Jilin University Changehun 130012 P. R. China

To decrease the moisture absorption and improve the mechanical properties of linen/polypropylene（PP） composites, linen was modified with silane N-β-（trimethoxysilyl） propyl]ethylenediamine（AAPTS）, surfactant trimethyloctadecylalmnonium bromide（STAB）, and both AAPTS and STAB, respectively. Fourier transform infrared（FTIR） spectra showed that the linen was successfully modified and alkyl chains were attached through different treatments. The linen and PP were compounded by melt compressing. The moisture absorption of linen was decreased after STAB and AAPTS-STAB modifications. The moisture absorption, mechanical property and thermal property of the composites were also characterized. The results show that the moisture absorption of the AAPTS-modified li- nen（F1） reinforced PP（PPF1） is 8.09%, which is higher than that of the unmodified linen reinforced PP（PPF）（7.89%）. The moisture absorption of the STAB-AAPTS-modified linen（F3） reinforced PP（PPF3） is 6.58%. The tensile strengths of PPF1 and PPF3 are 33.7 and 35.8 MPa, which are improved by 22.5% and 30% compared with that of PPF（27.5 MPa）, respectively. Nevertheless, the moisture absorption of the STAB-modified linen（F2） reinforced PP（PPF2） is decreased by 22.4%, and the tensile strength is improved by 30% compared with those of PPF. Scanning electron microscopy（SEM） analysis of the fractured surface confirms the good interfacial adhesion of PPF2 compared with those of other composites. Furthermore, the 5% mass loss temperatures of the composites are all higher than 290 ℃. Thus, linen modified with STAB is a promising reinforcement for biocomposites.

Optically pumped wavelength-tunable lasing from a GaN beam cavity with an integrated Joule heater pivoted on Si

Dynamically tunable laser sources are highly promising for realizing visionary concepts of integrated photonic circuits and other applications. In this paper, a Ga N-based laser with an integrated PN junction heater on Si is *** photoluminescence properties of the Ga N beam cavity are controlled by temperature, and the Joule heater provides electrically driven regulation of temperature. These two features of the cavity make it possible to realize convenient tuning of the lasing properties. The multi-functional Ga N beam cavity achieves optically pumped lasing with a single mode near 362.4 nm with a high Q-factor of 1394. The temperature of this device increases by 0–5℃ under the Joule heating effect. Then, electrical control of the lasing mode is demonstrated. The lasing resonant peak shows a continuous redshift of about 0.5 nm and the device also exhibits dynamic switching of its lasing mode. The lasing modulation can be ascribed to temperature-induced reduction of the bandgap. Our work may be of benefit for external optical modulation in future chip-based optoelectronic devices.
