Embodiment Construction
[0020] Such as figure 1 As shown, the fuzzy neural network decoupling controller 17 of the present invention is composed of two dynamic prediction modules 4, 5 and a fuzzy neural network system 3 connected in series, and the output ends of the two dynamic prediction modules 4, 5 are connected in series with the fuzzy neural network system The input end of 3 and the output end of the fuzzy neural network system 3 are connected to the compound controlled object 2 including the five-degree-of-freedom bearingless permanent magnet synchronous motor.
[0021] The output of compound controlled object 2 is the four radial displacements {x a ,y a ,x b ,y b}, an axial displacement z a and a rotational speed ω. The input of the first dynamic prediction module 4 is the radial displacement {x a ,y a}, axial displacement z a , Radial displacement given value and axial displacement given value The output of the first dynamic prediction module 4 is the composite control signal j ...
