Differential computation is necessary in velocity determination using carrier phase measurements from the global navigation satellite system (GNSS). A method of nonlinear tracking-differentiator is proposed to suppress both noise amplification and time delay introduced by differentiation. The carrier phase rate can be derived more precisely using the(More)
This paper presents a decentralized method to the problem of multiple Unmanned Aerial Vehicles (UAVs) cooperative search of an unknown area. Firstly, based on search map model, the multiple UAVs cooperative search problem is posed as a receding horizon (RH) optimization decision problem, and a RH based UAV search decision process is proposed. Then, this(More)
Robotic models have been used as one of the approaches to study fish locomotion. Therefore, this paper proposes an effective control scheme that enables robotic models to mimic fin-ray undulation kinematics of live fish. We found in the experiments of robotic fin undulation that the difference between the desired and actual trajectories can be significant.(More)
The particle swarm optimization (PSO) is a new swarm intelligence technique inspired by social behavior of bird flocking. In this paper, the optimal multi-objective optimization based on PSO (OMOPSO) is presented. Since the parameters determines the performance of the algorithm, the uniform design is introduced to obtain the optimal combination of the(More)
With the rapid development of UAV technology, remote measurement and control technology is vital to UAV, especially to the civil field. This paper builds an onboard embedded computing platform, establishes a measurement and control link based on mobile communication networks, puts forward an UAV position compensation method based on network time delay(More)
