1. fanjet measurement biases fault-tolerant gas circuit performance distributed and filters estimation method, which is characterized in that including followingStep:

  • Step A);

    the non-linear components grade dynamic general model of the above state of fanjet slow train is established, is divided according to componentSensor combinations establish distributed extended Kalman filter, realize the performance estimation to gas path component;

    Step B);

    adaptive algorithm is designed according to Generalized Likelihood Ratio method, senior filter overall situation estimated result is adaptively repairedJust, the response speed to mutation failure is improved;

    Step C);

    establish the isolation mech isolation test of subfilter, sensor occur biasing failure when, to failure subfilter carry out everyFrom redistributing the weight of subfilter, realize fault-tolerant estimation when biasing failure occurs for sensor.
