SBIR Phase II: Adaptive Control of Hot Isostatic Pressing (HIP) of Metal Matrix Composite Fabrication

小行星9500179 该小型企业创新研究（SBIR）第二阶段项目开发了一种先进的多变量自适应控制系统，用于金属基复合材料（MMCs）制造中的热等静压（HIP）操作。 第一阶段的计算机模拟表明，响应时间，短的三个因素，新的系统比标准的比例积分微分技术。 新系统采用模型预测控制和风险敏感优化控制的现代控制技术控制热等静压炉的温度和压力分布。 第二阶段项目的重点是在工业材料技术公司运营的大型热等静压炉设施上测试原型系统。在马萨诸塞州的安多弗。 新的熔炉控制方法有可能大大节省氩气使用量和电力，提高MMC产品（如钛基SiC纤维复合材料）的产量，并进行更可靠的环境/健康监测。

9500179 Mehra This Small Business Innovation Research (SBIR) Phase II project develops an advanced multivariable adaptive control system for hot isostatic pressing (HIP) operations in the fabrication of metal matrix composites (MMCs). Phase I computer simulations indicated response times, shorter by a factor of three, of the new system over standard proportional-integrative-derivative techniques. The new system controls temperature and pressure profiles in a HIP furnace using modern control techniques of Model Predictive Control and Risk Sensitive Optimal control. The Phase II project focuses on a test of the prototype system at a large HIP furnace facility operated by Industrial Materials Technology, Inc. in Andover, MA. The new approach to furnace control has potential for large savings in argon gas usage and electric power, for higher yields of MMC products, such as titanium matrix SiC fiber composites, and for more reliable environmental/health monitoring.
