本文简要介绍了C C复合材料TVCI工艺 (热梯度化学气相渗透 )原理 ,分析了其温度控制特点。针对该工艺高精度温度与温度梯度难以控制的不足 ,引入模糊控制理论 ,建立了基于自寻优的TCVI工艺温度模糊控制系统。仿真结果表明 ,该控制系统稳态精度高 ,规则易于调整 ,具有重要的实际应用价值 In this paper, the principle of CCl composite TVCI process (thermal gradient chemical vapor infiltration) is briefly introduced, and its temperature control characteristics are analyzed. Aiming at the insufficiency of high-precision temperature and temperature gradient control, the fuzzy control theory is introduced and a TCVI process temperature fuzzy control system based on self-optimization is established. The simulation results show that the control system has high steady-state accuracy and easy to adjust rules, which has important practical value
