Application of Hyperspectral Technology Combined With Bat Algorithm-AdaBoost Model in Field Soil Nutrient Prediction

Abstract: This paper proposes a hyperspectral soil nutrient estimation method based on the bat algorithm (BA)-AdaBoost model. The spectral reflectance, the first derivative of the reflectance, and the reciprocal logarithm of the reflectance are analyzed based on the 800 field soil samples and their hyperspectral data collected. The first derivative of the reciprocal logarithm of the reflectance and the sensitive band was extracted using the correlation coefficient method, and the correlation of the content of soil organ… Show more

“…Wang et al. (2022) developed a hyperspectral soil nutrient evaluation approach on the basis of the BA‐AdaBoost approach. The first derivative of reflectance, spectral reflectance, as well as reciprocal logarithm of the reflectance was examined on the basis of 800 field soil samples as well as their hyperspectral data gathered.…”

“…15,16 PMSM servo systems frequently employ conventional Proportional Integral Derivative (PID) control, which lacks precision and is ARTICLE pubs.aip.org/aip/adv susceptible to variations in internal parameters and external disturbances, making it challenging to achieve high-performance control in servo systems. 17,18 Sliding mode control (SMC) is a robust control method that is less affected by external disturbances and internal parameter variations, garnering significant attention in PMSM servo systems. 19,20 However, the chattering phenomenon, caused by the discontinuous switching term inherent in SMC, compromises control performance and introduces system vibrations, hindering practical applications.…”
