Three-degree-of-freedom trajectory tracking of the stratospheric airship is investigated. With a simplified planar dynamic model, an adaptive backstepping sliding mode controller is designed to keep the airship to globally asymptotically track a desired trajectory. Lyapunov functions are used to ensure the tracking performance when model parametric uncertainty and external disturbances exist. Simulation results demonstrate the effectiveness and robustness of the proposed control strategy.

With the innovation and development of unmanned aerial vehicle(UAV) technology, small UAV has also begun to attract the people's attention. Because of its characteristic of remote control, small size, low cost and other advantages, it already has a wide range of applications. However, the management of UAV has become a common problem throughout the world. It is a prerequisite which is how to detect UAV. Nowadays, the wireless signal of the UAV can help us detect it. In the low-altitude environment, due to the impact of noise, the first step is to identify the start-point of its single accurately. A detection algorithm for UAV signals with an adaptive threshold based on Gaussian mixture model(GMM) is proposed in this paper. The algorithm makes full use of the signal data characteristics, calculates the threshold using the GMM. Meanwhile, it does not need to set the fixed threshold manually. That means it can adaptively detect the wireless signal in a different noise environment.

Eye tracking technology is an important technology in the field of artificial intelligence(AI). Eye tracking will promote the development of human-computer interaction(HCI). Spot Center Corneal Reflex (PCCR) is an eye tracking technique that relies on pupils and reflected light spots. Therefore, it is significant to accurately locate the pupil position and reflected spot position. The traditional algorithm used the edge and the gray information of the image to extract the contours of the pupil and the spot, and then determine the location through the fitting. However, the collected images will be affected by many environmental factors, the boundary point and the fitting calculation will greatly affect the efficiency and stability of the algorithm. In this paper, a new method combining image gradient information with threshold segmentation is proposed. Gradient detection and threshold segmentation are carried out in the region of interest, and the pupil and reflection spot are extracted directly. So, this paper use the centroid method to calculate the center coordinates more accurately. The algorithm has a good robust performance to avoid noise and environmental effects. The algorithm used to develop human eye tracking system to achieve real-time eye tracking, while ensuring accuracy.
