在实践中

Direct Torque Control is a novel torque controlling technique which was proposed in 1980's. Although this technique has received a successful application in high-power ac drives recently, there are also a great deal of problems in the theories and practics which deserve to research. Centring around how to find and solve these prombles, theorical analyses, computer simulation and experimental studies are carried out in this dessertation.

There are some questions such as forest fire model selection, forest fire model updating, verifying simulation accuracy and so on in traditional forest fire spreading system. Study purpose is to build an innovative forest fire spreading simulation system based on DDDAS in this paper. The system can increase precision of forest fire spreading simulation by model base, model selection, model updating and so on. It can provide a strategic decision for forest fire save and new technologies demonstration for other related field of research. The research encompasses several major topics:(1) This paper brings up the term of dynamic data driven forest fire spreading simulation system and supplies new research approach and thought for forest fire spreading simulation study. The system framework was brought.
