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.

9500179 Mehra这个小型企业创新研究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(MMC)制造中的热等静压(HIP)操作。第一阶段的计算机模拟表明，新系统的响应时间比标准的比例积分导数技术缩短了三倍。新系统采用模型预测控制和风险敏感最优控制等现代控制技术，对热等静压加热炉的温度和压力分布进行控制。第二阶段项目的重点是在马萨诸塞州安多弗的工业材料技术公司运营的大型热等静压电炉设施中测试原型系统。这种新的炉膛控制方法有可能大大节省Ar气体使用量和电力，提高钛基碳化硅纤维复合材料等MMC产品的产量，以及更可靠的环境/健康监测。
