Traditional traffic lights control system works on a fixed-time basis, which can't optimize the time of traffic lights according to the change of traffic flow. To address this issue, this paper proposes an approach based on data-driven belief rule base for smart traffic lights. The main idea of this approach is using historical traffic data to predict traffic flow, and then determine traffic lights...
Quadrotor helicopter is an increasingly popular rotorcraft platform for unmanned aerial vehicle (UAV) study. Development of a mathematical model with accurate model parameters for quadrotor is extremely beneficial to control the system. But accurate measurement of numerous vehicle parameters would be especially challenging. In this paper, a system identification method for the quadrotor model parameter...
While a vehicle driving in the street below tall buildings or viaduct, GPS receiver may receive the satellite reflected signals or may not receive satellite signals. That will cause serious positioning errors. This is called as multipath transmission error of global satellite positioning system in the metropolitan area of a city. With using the driving-view image fetched from the video of vehicle...
The ability to transition between vertical and horizontal flight is of great importance to convertible unmanned aerial vehicles. A novel convertible UAV-a Quad Tilt Rotor UAV (QTR UAV) was designed, which could operate as a quad rotor as well as an airplane by means of transition maneuver. This paper focuses on the trajectory tracking control for the hovering mode and acceleration maneuver which is...
This paper investigates the synchronization control problem for a group of networked Lagrange systems without relative velocity measurements. Distributed observers are proposed to estimate the neighbors' velocities. Based on the estimated states, the distributed controllers are designed to achieve the synchronization of the networked nonlinear systems. In contrast to other approaches, the development...
