Abstract


Multicriterial control synthesis requires electric machine viewed as a multidimensional object. The paper considers the application of the method for synthesizing multidimensional control of a synchronous machine with electromagnetic excitation of a high-speed electric drive. The general laws governing the change in the state of an electric machine for a minimum time and the solutions of multicriteria optimization are found. The methodology of synthesis of multidimensional control, providing along with the formation of the electromagnetic torque regulation of the basic properties of the electric drive of various types using the example of a synchronous machine with electromagnetic excitation. Using variational methods and the inverse model method for a nonlinear multidimensional object, organized control provides a typical character of the formation of an electromagnetic moment in minimizing heat losses in conditions of minimum reactive power, taking into account the nonlinearity of the magnetization characteristic of a synchronous motor. A rapid change in the rotor current under voltage-limiting conditions is achieved by using the effect of the demagnetizing action of the armature reaction. The results of modeling are presented. Losses in steel are not taken into account.
