Research and application of steady flow intake control method in icing wind tunnel engine intake simulation system
In view of the problem of steady flow intake control of engine intake components in icing wind tunnel,and by combining the working principle of engine intake simulation system available with intake conditions,the Kalman filter model-free adaptive control method was adopted;by establishing the system dynamic linearization data model,and using the Kalman filter to make a true value estimate of the actual dynamic flow output,the difference between the estimate and the expected value was calculated through the dynamic data model,the input amount of the speed of the pumping equipment of the system was obtained,and the steady flow intake control was carried out.Finally,it was applied to the anti-icing test of the intake components of a certain type of engine.The test results showed that the engine intake simulation system performed stably and reliably,the output intake flow met the test requirements,and the control accuracy of the intake air steady flow reached 0.1 kg/s.
