摘要: In this paper, a nonlinear signal-correction observer (NSCO) is presented for signals correction and estimation, which not only can reject the position measurement error, but also unknown velocity be estimated, in spite of existence large error intense stochastic non-Gaussian noise. For method, signal required to bounded. The NSCO developed position/acceleration integration, it applied an unmanned aerial vehicle (UAV) navigation: Based on NSCO, flying quadrotor UAV are estimated. An experiment conducted demonstrate effectiveness proposed method.
