Variable universe fuzzy control based on intelligent control technology is proposed in this paper for the hypersonic flight process of nearspace vehicle (NSV) with severe changes of aero-dynamic parameters and susceptibility on the external disturbances. And the contraction-expansion factor of the fuzzy control is given to modify the scale of universe and reduce the computational cost. By adopting...
For the obvious characteristics of time-varying nonlinear controlled object, in order to improve the control performance, the appropriate adaptive control strategy could be used. Based on the research object system of a certain amount of input to control variables, according to Lyapunov stability theory, the research object system input/output variable a model reference adaptive control system was...
Standard Kalman Filtering leads to divergence because of inaccurate system model and noise statistic. Researchers have taken relative studies about Kalman filtering optimization method. But now most studies are based on applications, such as integrated navigation system, so most of these methods are lack of general applicability. This paper starts from innovation-based adaptive estimation (IAE) filtering...
