This paper investigates the three-dimensional (3D) curved path following problem using fixed-wing unmanned aerial vehicles (UAVs) in the presence of constant wind disturbance. Vector field based approaches are used as the solution. Two vector fields are first developed, one is the tangent vector field based on path tangent vector and coordinate transformation, and the other is the combined vector field based on the combination of a conservative vector field and a solenoidal vector field. A unified jointly saturated course rate and saturated climb rate controller is designed based on the proposed vector fields. Simulations are conducted to demonstrate the effectiveness of the proposed approach.
Aim at the problems of the lower reusing of software, the poor expansibility of software system and the lower cooperation between the designers, a common electric dressing shop was designed using the technology of the...

College students often collaborate in some projects or contests with other students from different majors, but current team seeking system has some limitations on finding teammates. In this paper, we design a multi-tenant college sustained team seeking system, aiming at establishing a sustained team among college students who have similar interest. We present the architecture, core modules, and some emerging techniques to design such a system. The evaluation of query efficiency and page loading speed are present at last.

This paper is concerned with the problem of tracking target with multiple sensors in the presence of unknown dynamic bias. A suboptimal adaptive two-stage Kalman filter(ATKF) is designed with two reduce-order filters to estimate the target state and the dynamic bias in parallel when the bias model information is incomplete. Moreover, a distributed adaptive two-stage Kalman filter(DATKF) is developed for multi-sensor system based on the ATKF. The effectiveness of the ATKF and the DATKF are illustrated by the Monte Carlo simulation results.
