For the nonlinear coupling control problem induced by the maneuver flying with high angle of attack of the hypersonic vehicle, the dynamic inversion is used to realize the decoupling of the attack angle and bank angle dynamics. For the model uncertainty, parameter perturbation and outer disturbance, the estimation and compensation of the disturbance moments is carried out by the extended state observer...
Last decade has proven a drastic change in information technology. Service oriented architecture (SOA), as a new generation of software technique, comes into being to face the challenge of the soaring business varieties and complexities. This paper offers a discussion of service properties and appoints 6 key service properties for SOA. Then, the paper puts forward a role-based reference model for...
In the multistage reliability growth tests with instant and delayed fix modes, the failure data can be assumed to follow Weibull processes with different parameters at different stages. For the Weibull process within a stage, by the proper selection of prior distribution form and the parameters, a concise posterior distribution form is obtained, thus simplifying the Bayesian analysis. In the multistage...
