Article
A triple modular redundant (TMR) control system achieves high reliability by replicating data and all processing at three independent nodes, so this control system is widely applied in many fields. Loongson Micro Computer Unite (MCU) is designed by The Institute of Computational Mathematics and Scientific/Engineering Computing of Chinese Academy of...
Article
We propose two nonlinear approaches for the autonomous transition control of two vertical/short takeoff and landing aircraft. The first aircraft, referred to as the V-1 aircraft, is a fixed-wing fighter equipped with a vectored thrust and lift fan. The second aircraft is a tilt rotor. We provide nonlinear models for the transition from hover to for...
Conference Paper
In this article, design and implement of anti-impact and over-loading projectile conform al antennas for GPS is introduced. First step, material and thickness of base for antennas should be chosen, then width and length of antennas is calculated, next step to polarize antennas and give location of feed points. The designed antenna is emulated and a...
Conference Paper
This article presents the implementation of mission planning for unmanned aerial vehicles (UAV). A safe-ring method for real-time path planning of UAV is proposed. Threat modeling, different types of reconnaissance are discussed before the algorithm is described. Kinematical constraints are satisfied with a model which has the same structure as the...

... 基于上述问题,本文着手于差异化安全计算机的研究, 从硬件和软件两方面采取异构的方式,即采用架构不同的 处理器,在处理器上运行不同的操作系统,以此来解决某 些共因故障带来的安全性问题 [6][7][8][9][10]。 具体而言,本文在硬件上采用了两种不同的处理器架 构:Coldfire MCF54455和ARM ZYNQ,软件上同样采用 了两种不同的实时操作系统:VxWorks和QNX [11][12][13][14] ...
... The research on the control system design for the short takeoff or vertical landing (STOVL) vehicles is comparatively rich. Reference [11] applied the dynamic inverse theory and designed the controller for the F-35B reduced-scale vehicles for the transitional flight control, and the simulation results reflected an excellent tracking performance. Reference [12] used an L1 adaptive [13] inner-loop controller and designed a roll-horizon landing deceleration and landing strategy for the hybrid-wings vehicles. ...
... There are few literatures about BDS/GPS antenna designs suitable for high-shock projectile applications. The sizes of the conformal antenna arrays which are printed on conical surfaces in [24][25][26][27] are still not small enough. In [28], a CP microstrip antenna of small size and CP character conformal with the cross section of a missile is proposed. ...
