This Small Business Innovation Research (SBIR) Phase II project will develop and test algorithms for active control of blade vibration and engine stability (stall and surge) using an eddy current sensor (ECS) array. The approach utilizes signal analysis and diagnostic tools in active control algorithms for the detection of engine faults. Phase II will extend the functionality of the ECS system beyond diagnostics to active and automatic real-time control of gas turbine engines.An ECS array is currently the favored sensor system for installation on the Joint Strike Fighter, in which a software system upgrade capable of using ECS data to compute the necessary indicators and estimate the disturbances needed is desirable for active vibration and engine stability control. It would reduce the number of new sensors needed for active control and potentially save millions of dollars. Large commercial markets are indicated in commercial aircraft and gas turbine power plants.

该小型企业创新研究（SBIR）第二阶段项目将开发和测试使用涡流传感器（ECS）阵列主动控制叶片振动和发动机稳定性（失速和喘振）的算法。 该方法利用主动控制算法中的信号分析和诊断工具来检测发动机故障。 第二阶段将把ECS系统的功能从诊断扩展到对燃气涡轮机发动机的主动和自动实时控制。ECS阵列是目前安装在联合攻击战斗机上的最受欢迎的传感器系统，在这种战斗机中，软件系统的升级能够利用ECS数据计算必要的指标和估计所需的扰动，这对于主动振动和发动机稳定性控制是理想的。 这将减少主动控制所需的新传感器数量，并可能节省数百万美元。 商用飞机和燃气涡轮机发电厂显示出巨大的商业市场。
