With this approach, a mathematical model of ASVG is developed. The method is simple and can be used to analyze the detailed internal properties of an ASVG. It overcomes the disadvantages of the two methods generally used, one is a method for modeling an ASVG by getting differential equations according to the topology of the ASVG circuit, which is very complicated and it is difficult to get a unified model expression of an ASVG; the other is a method for modeling an ASVG by considering the whole ASVG as a voltage source, which is too simple to analyze the detailed internal properties of ASVG.

该方法既克服了根据ASVG装置拓扑结构列写微分方程组的建模方法过于复杂且不易获得统一模型表达式的缺点，同时又克服了将ASVG装置等效为电压源的建模方法太简单而无法用于分析ASVG装置内部性质的缺点，具有建模简单又能分析ASVG装置的内部性质的优点。

Thirdly, fuzzy control method and PID method were used respectively to design temperature self-adjustment controller of carbon fiber concrete laminate beam,by the MATLAB simulation it is found that the PID method has higher speed but is more sensitive to the fluctuation of system parameter ,it is suit to the regulating when the heat transfer coefficient fluctuates diminutively and the structure has little heat transfer with the environment;fuzzy control can be adapt to the parameter variety in a large scale , it is suit to the regulating when the heat transfer coefficient fluctuates greatly.
