Description
Summary:The paper is devoted to the equivalent transfer function calculation of signal-adaptive controller of the electromagnet excitation current, which is an inner control loop in cascade control system of automatic correction system of rotor radial position updating of micro electric drive, using in ultraprecision processing systems. A new approach of solving the problem of stabilizing the rotating element of motor, based on active current updating of the spatial position is offered. The calculation of automatic control algorithm is done using the method of signal-adaptive inverse model. The paper describes the way of constructive implementation of this method, structural synthesis methodology of control law, as well as the results of simulation, confirming potential of conducted research.
