DISCRETE MATHEMATICAL MODEL OF THE ELECTROMAGNETIC BEARING

It is shown that for synthesis of digital regulators of a control system by the electromagnetic bearing the knowledge of its discrete mathematical model is necessary. The continuous mathematical model of the electromagnetic bearing taking into account eddy currents is considered. The discrete transfer function of the electromagnetic bearing considering the zero order hold device which function is carried out by the digital power converter is found. It is shown that the received transfer function allows to formulate at a design stage requirements to computing capacity of the microprocessor.
