Due to the complex hysteresis phenomenon at a high angle of attack (AOA), modeling of unsteady aerodynamic coefficients usually encounters the problem that the parameter vector is too long and the simulation accuracy is not high. The article proposes an improved state-space model based on...

This article describes how in recent years, models-based software reliability test methods have been a hot topic. In order to summarize the research results of the reliability test models created in recent years, and to find new research hot topics on this basis, two kinds of test models are in...
