摘要： A flutter control system for a turbine includes a processor. The processor is configured to detect blade flutter of a turbine. The blade flutter indicates that blades of the turbine are in a deflected position different from a nominal operating position. The processor is configured to control operational parameters of the turbine that reduce or eliminate the blade flutter to improve the reliability and efficiency of the turbine.

摘要： A method of estimating a remaining life of a valve is disclosed, comprising steps of collecting valve actuation force data; calculating an average value of the valve actuation force data in at least one of a plurality of actuation cycles; estimating a remaining life of the valve using a model based on the calculated average values of the valve actuation force data obtained from the at least some of the plurality of cycles and a valve actuation force limit. A valve controller (20, 21) of estimating a remaining life of a valve is also disclosed.

摘要： A calibration apparatus 120 is configured to calibrate a magnetostrictive sensor. The magnetostrictive sensor 110 is configured to measure an object 900 and comprises a sensing element positioned adjacent to the object. The calibration apparatus comprises an estimation device 130 and a calibrator 140. The estimation device 130 is configured to estimate at least one of a gap between the sensing element and the object and a temperature of the object to obtain at least one of an estimated gap and an estimated temperature, based on geometric information, an excitation signal and an output signal of the magnetostrictive sensor, and geometric information of the object. The calibrator 140 is configured to reduce an effect on the output signal of the magnetostrictive sensor imposed by variations in the at least one of the gap and the temperature, based on the at least one of the estimated gap and the estimated temperature, to obtain a calibrated output signal.
