In Vehicular Grid Sensor Network (VGSN), because the operation of individual vehicles and mobile speed and direction, contact between them fragile and unstable. It has multicast links suddenly fail to overcome the problems, so that the message flows to each node, and increase the volume of traffic control. In this paper, we propose a fuzzy-based target tracking scheme that will re-route the link path...
This paper is based on the dynamics characteristics of the air-cylinder; develop the air-cylinder piston wear ring axial deflection with LuGre model, then use the MATLAB to simulate the axial deflection and get the relevance between axial deflection and cycles. Meanwhile, set up the air-cylinder piston durability experimental platform, achieve a large number of data and compared with simulation data,...
Sequencing-by-synthesis technology takes us a step closer to the promises of personalized medicine by enabling affordable and fast DNA sequencing. Its accuracy, however, is fundamentally limited by the imperfections of the underlying biochemical processes and signal acquisition noise. In this paper, we focus on pyrosequencing systems, derive a mathematical model of the signal they acquire, and develop...
Radio frequency identification is applied to the indoor location system of store environment in the paper. According to the radio frequency communication signal time difference between reader and merchandise tag, it can be easy to measure goods spatial position. In the research, we use smoothing method to construct the original measured data to degrade NLOS error. Then improved genetic algorithm is...
The purpose of this research is to accomplish the ZPETC (Zero Phase Error Tracking Control) Path-Tracking gain-scheduling control design and real-time multi-task flight simulation for the automatic transition of tilt-rotor aircraft. Firstly, we select 20 flight equilibrium points during the automatic transition through the trim operation. For each equilibrium state, we can get a set of Jacobian matrix...
The real-time multi-task simulation of a 3-leg 6-DOF high performance platform system based on RT-Linux operation system is presented in this paper. The new architecture is setup by three extensible legs sliding on three linear slide-rail each actuated by a synchronous linear servo motor. The extensible legs are actuated by inductive AC servo motors. In the meantime, the inverse and forward kinematical...
This paper develops a motor-driven massage artificial electro-mechanical manipulator system with intelligent biomedical sensing-monitoring capabilities and constructs the path of massage process by using CCD image processing technique. In this paper, we integrate a versatile inter-digital electrocardiograph (ECG) into the manipulator system and construct a massage path by using twin CCD image processing...
The paper presents a dual closed-loop vector control system based on DSP for asynchronous motor which is a multi-variables, nonlinear, strong coupling and time-varying system and is difficult to determine precise mathematical model because of changes in motor parameters and load fluctuations in factors. Speed controller uses a parameters self-adjusting fuzzy controller and flux observer uses an improved...
