Solid Ramjet Motor Flow Measurement and Application of Kalman Filter
摘要
Abstract
In order to improve the accuracy and response rate of solid ramjet motor inlet flow meas-urement, the averaging velocity tube flowmeter ( delta flowmeter) is used for inlet flow rate measuring, the high speed and high precision measurement system is established based on PLC and PC, the Kalman filter which is self-adaptive and responds in real time is designed to eliminate the random errors in the measuring system.The testing results show that the precision of solid ramjet motor inlet flow measuring is promoted and the responding speed of this measurement system is high enough for practical use.关键词
