The paper presents a method of inverse model for the synthesis of multidimensional control of an asynchronous machine with a short-circuited rotor, where electric machine is considered as a multidimensional object, characterized by the existence of two input control actions and two output values, nonlinearly related to controlled variables. Using inverse model method with linearization by output the formation of electromagnetic torque is said to be aperiodic and is implemented in the conditions of simultaneous control of reactive power to its minimum value. Using the La grunge method in Pontryagin form, electromagnetic torque is changed and reactive power is regulated to its minimum value at minimum time. Due to the lack of preliminary magnetization, control with minimization of reactive power of medium-power asynchronous machine can improve integrated assessment of the efficiency during the transition process to (4-6) %
Key words: AC electric drive, asynchronous machine, minimization of reactive power, inverse model method, aperiodic nature of electromagnetic torque formation, Lagrange method in Pontryagin form.
