For achieve accurate estimate of State of Charge (SOC) in the management system of battery, a novel algorithm that combined the fuzzy information granulation (FIG) and support vector regression (SVR) was proposed in this paper to predict SOC. This algorithm use radial basis function as SVR kernel. To establish SOC prediction model of Lithium battery, the current, voltage and granulated time are regarded...
Directing to surplus force problem of the elect-hydraulic load simulator, aimed at multiple inputs multiple outputs control system this article proposes a decoupling control method to solve the force-position coupling problem. This method broke the traditional compensation method. Taking asymmetric cylinder as the object, a mathematical model of system is build firstly, and then a decoupling controller...
Historic settlements have adapted to the local climate and geographical environment accommodating residents over the years. Rich and precious scientific design concepts, including the site selection, the layout, and the building materials, should be investigated extensively. Different historic settlements will be presented and discussed, in terms of different design elements and urban planning forms,...
The paper builds the fault diagnosis model and optimizes the input interface of the model by normalizing the initial data of the vibration parameter for the automobile engine, carrying on information fusion and adopting the Adaptive Neural Fuzzy Interference System (ANFIS). The recognition rate of the model reaches 91.25% under the test of field test data. The experiment indicates that the model enjoys...
Mathematical models play an important role in the studies of modern economics. But in many fields of economics, it is difficult to build mathematical models for complex phenomena. So data mining is getting more and more popular in discovering the potential pattern of economic knowledge from databases. As a powerful tool for data mining, rough set theory has been widely used. In this research, we draw...
For all sorts of problems in the procedure of high-power induction motor's starting, as well as the drawbacks of traditional starting method. This paper proposed the full-voltage starting method of high-power induction motor with dynamic reactive power compensation, introduced its principle, and studied the control strategy of full-voltage starting with dynamic var compensation emphatically, established...
This paper aims to prolong the heat pump frost time and reduce its growth with heat recovery facility, which should mix the exhausted indoor and outdoor air before entering the evaporator. An ideal mathematic model is developed for heat transfer, frost generation and airside pressure drop. The properties of the mixture would be obtained by solving the mass and energy conservation equations. A parametric...
