Wireless sensor network (WSN) is inevitably subject to node failures due their harsh operating environments and extra-long working hours. In order ensure reliable correct data collection, WSN fault diagnosis necessary. Fault of nodes usually requires the extraction features from original collected data. However, different types faults sometimes have similarities, making it difficult distinguish represent in results, these indistinguishable are called ambiguous information. Therefore, a...
Compared with traditional mechanical inertially stabilized platform (ISP), magnetic suspension ISP (MSISP) can absorb high frequency vibrations via a bearing system five degrees of freedom between azimuth and pitch gimbals. However, force acting rotor stator will introduce coupling torque to roll Since the disturbance bearings has strong nonlinearity, classic state feedback control algorithm cannot bring higher precision for MSISP. In order enhance accuracy MSISP, compensator based on radial...
Three-axis inertially stabilized platform( ISP ) is used to stabilize the line of sight( LOS an optical imaging sensor, such as CCD digital camera or television. But due existence mass imbalance in ISP, torque inevitable under effect slide vibration mobile vehicle, which will lead degrade ISP's accuracy and degeneration image quality. In order attenuate influence torque, a better practical solution devised. The cause - linear acceleration sensor can be measured fed forward gimbal drive...
This paper studies the impact of accelerometer output error on levelling accuracy in mode airborne remote sensing stabilized platform. On basis that signal is non-stationary, a non-stationary time series model ARIMA(3,0,1) established, with which an adaptive Kalman filter designed. In filter, online correction method for forgetting factor based real-time measurements presented, achieving automatic adjustment gain. The and are applied to platform principle prototype made by our research...
Ensemble learning, as a kind of method to improve the generalization ability classifiers, is often used model effect in field deep learning. However, present ensemble learning methods mostly adopt voting fusion combining strategies. This strategy has difficulty mining effective information from classifiers and cannot effectively reflect relationship between different classifiers. based on evidential inference rule (ER rule) can excavate internal relationships among certain interpretability....
The main purpose of this paper is to investigate the control method for a three-axis ISP. Firstly, simplified geometry model was built by Solid works. Then, Simulink composed bodies, joints, constraints, and force elements ISP obtained from 3D via SimMechanic toolbox. On basis model, classical PID controllers three closed servo loops were designed applied system under friction disturbance being taken into account. simulation results show that compared roll pitch gimbals, dynamic performance...
Three-axis inertially stabilized platform (ISP) is a key technology in airborne remote sensing system, which used to support an optical imaging sensor and hold the line of sight (LOS) vertical earth, whose accuracy has great effect on image quality. Presently control method for ISP mostly focused conventional PID control, disadvantages low accuracy, bad disturbance rejection capacity. A novel observer(DOB) devised this paper aiming attenuate influence disturbing torque enhance ISP,...
The prediction of processor performance has important reference significance for future processors. Both the accuracy and rationality results are required. hierarchical belief rule base (HBRB) can initially provide a solution to low accuracy. However, interpretability model traceability still warrant further investigation. Therefore, method based on interpretable (HBRB-I) global sensitivity analysis (GSA) is proposed. yield more reliable results. Evidence reasoning (ER) firstly used evaluate...
