Example Embodiment

[0027] The implementation of the present invention is: firstly, a prototype body of a five-degree-of-freedom bearingless permanent magnet synchronous motor is constructed based on a three-degree-of-freedom AC and DC radial-axial hybrid magnetic bearing and a two-degree-of-freedom bearingless permanent magnet synchronous motor. A Clark inverse transform, three current tracking inverters, a linear power amplifier, a five-degree-of-freedom bearingless permanent magnet synchronous motor and a load constitute a composite controlled object as a whole. The composite controlled object is equivalent to a static coordinate system The 11th-order differential equation model of, the relative order of the system vector is {2,2,2,2,2,1}. A static neural network (3-layer network) with 17 input nodes and 7 output nodes plus 11 integrators -1 It constitutes a neural network inverse of the compound controlled object with 6 input nodes and 7 output nodes. And by adjusting the weights of the static ne...

Abstract

This invention relates to permanent simultaneous motor control system based on NN with five free degree and with no bearing, which is characterized by the following: one two-free degree with no bearing simultaneous motor, one three-free degree alternating radium and axis direction mixed magnetic bearing form one sample body; three Clark anti-conversion, three current tracing anti-converter and one linear power amplifier, sample machine and its load work as one integration to form compound controlled subject; using static NN summer through study formula to form NN reverse for non-linear dynamic decoupling control on five free degrees bearing.
