A nonlinear fault-tolerant control and active vibration suppression design approach is presented in this paper. In the presence of flexible satellite with actuator faults, orbit control force and environment disturbance, a nonlinear adaptive fault-tolerant control approach is designed for the flexible satellite attitude control system. The control law is based on H-infinite adaptive method and designed...
Model-based signal processing methods, such as matched-field processing, are concerned with exploiting the combination of the sound propagation physics in an ocean waveguide and the observation data. As such, they require accurate knowledge of the ocean acoustic environment. This paper presents an approach of environmental inversion via acoustic data assimilation (ADA), intended specifically to reconstruct...
Displacement amplification ratio and input stiffness are significant design characteristics for an ultra-precision positioning flexure-based compliant mechanism. Early and accurate performance prediction models can significantly improve the reliability and availability of product in the field of ultra-precision positioning, but Existing theoretic models cannot predict its characteristics accurately...
In this paper, we study mean first-passage time (MFPT) for random walks on a network through edge iteration. The feature of this kind of network is that every existing edge gives birth to finite nodes at each step. According to the network structures, we obtain the analytical expression for MFPT, which shows that the MFPT grows as a power-law function with the number of nodes in the large limit of...
This paper presents a new framework for the assembly planning of aircraft which integrates assembly sequence planning (ASP) with CAPP on the basis of the standardized mathematical model of polychromatic sets. This paper fulfills three main tasks including the selection of location mode and assembly equipments, assembly sequence planning, and assembly process planning based on a unified model, which...
The present study extended previous research by proposing and empirically testing the relationship between trust in leader and team performance and the model of mediating processes underlying the relationship. The survey was conducted in 75 work team from several cities in China. The hierarchical regression results showed that trust in team leader involved cognition-based trust and affect-based trust,...
Based on reduced model of double-fed direct current motor system (DFDCMS), the state space description and its key states of DFDCMS are advanced. The two wheeled robotpsilas kinematics model and motion-actuator model are analyzed, the state observer based on extended Kalman filter (EKF) of the two wheels mobile robot (TWMR) is used to filter the signal with interference and get the key states. There...
