METHOD OF TEST OF ELECTRON REGULATORS OF GAS-TURBINE ENGINES AND DEVICE FOR ITS REALIZATION Russian patent published in 1997 - IPC

FIELD: automatic adjustment of aviation gas-turbine engines, tests of control systems and of their components. SUBSTANCE: in compliance with proposed method there are formed unidimensional array of constant values X=(x) with dimensionality M embracing whole range of possible changes of output coordinate x of engine and unidimensional array of controlling action U = {U} having dimensionality N. 3-D array of transition probabilities P=(p) having dimensionality N x M x M is constructed on basis of these two unidimensional arrays. Each element P_jkg of it presents probability of transition of engine from state {X_k} on i-th control step into state {X_q} on(i-th +1) control step under effect of control action U_j. Value of probabilities P is found from a priori statistic data on operation of given particular gas-turbine engine. Then value j is chosen under mode of stochastic modelling on each i-th modelling step by value of controlling coordinate U(ti) generated by tested regulator from condition . Value k is chosen by value X(ti) from condition and value of output coordinate (ti+1)= Xq is formed on basis of MonteCarlo method. After this it is sent through simulator of transducer to regulator and device for realization of proposed method. In device output of simulating computer 4 is connected to first input of first key 5 which output is connected to input of simulator of transducer 6 and which second input - to output of stochastic modelling unit 7. First input of this unit is connected to second output of second key 3 which first output is linked to input of simulating computer 4 and which input is connected to output of simulator of actuator 2. Controlling inputs of keys are connected to output of unit 9 controlling keys. Second input of stochastic modelling unit 7 is connected to output of generator 8 of random numbers. EFFECT: enhanced reliability of automatic control. 2 cl, 2 dwg
