Abstract
This paper deals with the operating modes of a 3-degree-of-freedom (3-DOF) electric machine. The design of such a machine allows the rotor axis to rotate along two angular coordinates in a limited range of angles. This is necessary for the machine to operate as part of a small-sized, high-speed precision target detection and tracking system. Based on the 3-DOF machine dynamics model, a block diagram of a servo system has been developed for controlling the rotor motion trajectory at two coordinates. Examples are given of the implementation of rotor motion trajectories with linearly increasing Examples are given of the implementation of rotor motion trajectories with linearly increasing, as well as described by an Archimedes spiral reference signals described by an Archimedes spiral reference signals. Dependencies of the modules of the relative accuracy of rotor movement along given trajectories on the system tunings were obtained. Ref. 12, fig. 9, table. Keywords: control system, motion trajectories, three-degree-of-freedom electric machine.
