This paper focuses on identification of systems with rate saturation nonlinearity, considering measurement and process noises. A methodology is proposed to estimate the parameters of linear dynamics along with the upper and lower limits of rate saturation, using only system input and output. The methodology consists of four correlative parts which sequentially are choosing sine sweep signal with appropriate...
This paper introduces the principle and method of a new design of the experimental platform for Unmanned Aerial Vehicle (UAV) system identification based on LabVIEW, which is a popular tool for developing virtual instrument and is also widely used in many applications in the fields of measurement and control. Inherited with the Graphic programming and data stream driving mode from LabVIEW, the new...
This paper presents a method to accurately identify the yaw-dynamic model of an unmanned helicopter. First, the model's structure is established by dynamic analysis. Then the model is reconstructed into a combination of three second-order subsystems. As the distribution of the damp ratios and natural frequencies of a second-order subsystems is limited, the model can be accurately identified from real-flight-test...
