This paper proposes a on-line modeling and control approach through Takagi-Sugeno (T-S) fuzzy-neural model for a class of generalized multiple input multiple output (MIMO) nonlinear dynamic systems with external disturbances. Nonlinear systems are exactly formed a linearized system via the mean value theroem, and then the T-S fuzzy-neural model can approximate the linearized system. Then on-line identificatoin...
Wind tunnel testing is the effective method to research high speed train aerodynamics. It is one of the key steps to ascertain the model scale for wind tunnel testing, because scaled model is always introduced into wind tunnel testing, due to the huge body. Based on the structure of aerodynamic and aero-acoustic wind tunnel, using computational fluid dynamics (CFD), focus on middle car of three connected...
Recently, because of the blind spot of oversize vehicle, accident happened repeatedly when the vehicle turned right. Therefore, to solve the problem, an embedded system based on computer vision technology which can early warn driver is proposed. Capture image with CCD camera, extract the background by using background subtraction, and build background model by the way of weighted average. After that,...
