In this paper, the fault detection problem for networked control systems is investigated by adopting mixed H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> and passive performance. Moreover, randomly occurring missing data over network considered to be more practical. By applying filtering-based residual generator, sufficient conditions can established such that augmented error system achieve given performance index. obtained results,...
At present, most large machinery and vehicle engines are electronically controlled but their electronic control systems too expensive to be popularised applied in small gasoline with relatively low prices. Therefore, still use mechanical speed regulators. Mechanical regulators not only have the defects of inertia lag, friction resistance, inherent regulation like, also disadvantage that dynamic performance steady cannot combined, which is suitable for increasingly improved engines. This...
Abstract In accordance with safety requirements for the near-surface disposal of low and medium-level radioactive solid waste, accurate identification measurement radionuclide types activities within steel boxes containing such waste are necessary. Conventional sampling techniques impractical due to nonuniform internal filling distribution in used storage. Nondestructive analysis offer significant advantages by providing comprehensive measurements without causing damage or generating...
This paper uses the modified Backstepping (BS) Control method and Dynamic Allocation (DCA) to solve problem that when fighter aircraft under different flight conditions, it will be adaptively tracking commands. Firstly, we introduce classical Lyapunov backstepping control method, then propose a applied by general system model. Finally, for common allocation can't compensate ignoring actuator dynamics, dynamic is introduced, successfully design of whole closed loop system. The controller...
The application of infrared simulation technology (infrared lamp) in vacuum thermal test spacecraft has been studied China since 1988.Up to now, the research lamp at home and abroad mainly focuses on technology, product screening quality control. However, due irreducible defects quartz tube itself, human error other factors. Therefore, failure is inevitable process test. At present, little done effect remedial measures. In this paper, common array analysis. effects different regions...
Abstract The thermal test of spacecraft has a large demand for the program-controlled power supply, which was configured as array. In this paper, intelligent management technology supply is researched. Base on analysis history fault type detection studied. Then, combined with redundancy switching, an on-line switching device designed. Through verification experimental, experimental results show that system can quickly realize and positioning finish online to backup within second-level time....
Abstract Positron Emission Tomography (PET) is a nuclear imaging modality used in clinical diagnostics and biomedical research to show metabolic processes an organism. Movable PET has great significance for the practical application of tumor diagnosis. In this paper, we propose panel system with high portability, further evaluate virtual-pinhole (VP-PET) higher spatial resolution. To resolution prototype, build rotation stage coupled two detector modules. detectors are composed 12 × LYSO...
