In this paper, we focus on the modeling problem of the multi-frequency signals which contain
many different frequency components. Based on the Newton search and the measured data …

For the bilinear system with white noise, the difficulty of identification is that there exists the
product term of the state and input in the system. To overcome this difficulty, we derive the …

Quadcopters are widely used in a variety of military and civilian mission scenarios. Real-
time online detection of the abnormal state of the quadcopter is vital to the safety of aircraft …

This paper is concerned with the joint estimation of states and parameters of a special class
of nonlinear systems, ie, bilinear systems. The key is to investigate new estimation methods …

Based on the collected weather data from the agricultural Internet of Things (IoT) system,
