A capacitor-isolated structure with brightness and color controlling for multicolor LED strings is proposed. Such structure mainly plays the role of current-balancing and color mixing. Moreover, in order to decrease the color shift, the current amplitude of LED strings is controlled constant. The luminous flux and chromaticity coordinates are regulated through controlling the sum and ratio of duty...
In this paper, we design high-order internal models learning law for impulsive differential systems to track the varying reference accurately by adopting a few iterations in a finite time interval. We present convergence analysis for the P-type and D-type updating law. Finally, two examples are given to illustrate our theoretical results.
To solve the problems of the nonlinear model of INS/GPS integrated navigation system, the advantages and disadvantages of the Kalman filter (KF), sigma-point Kalman filter (SPKF) and square-root sigma-point Kalman filter (SR-SPKF) were discussed. The arithmetic of adaptive square-root sigma-point Kalman filter (ASR-SPKF) was proposed, which was the most perfect arithmetic for the nonlinear system...
Aiming at the limitation of research on enterprise competition model, the idea to apply complex adaptive system theory to the enterprise competition was proposed. Secondly, referring to the modeling scheme of Holland's echo model, an applied model of agent-based enterprise competition was built. Finally, according to develop the program of Object-C based on swarm, the dynamic competitive behavior...
Predicting stock performance is a very large and profitable area of study. A large number of studies have been reported in literature with reference to the use of artificial neural network in modeling stock performance in western countries. However, not much work along the approach to neural network based on agent has been reported. This thesis focuses on the development and the simulation of a stock...
Stock market is an extremely complex nonlinear dynamic system. Neural network has the capability of approximating any nonlinear system and the specialty of self-learning and self-adapting, attempt to substitute neural network for agent. Secondly, refer to the modelling scheme of Hollandpsilas stock market model, an applied model of stock market using ERA scheme was built. Finally, the dynamic evolvement...
