Al' R. The investigation of transient processes of power supply node of actuating induction motors as element of control system.

Object of investigation- power supply node of actuating induction motors as element of control system. Aim of investigation-elaboration of methods of analisys of transient electromechanical processes of power supply node of actuating induction motors with squirrel-cage rotors and massive hollow ferromagnetic and nonmagnetic rotors as element of control system with accounting of instant commutational distributions of currents in magnetisation windings. Theoritical results and novelty- the method of forming of mixed nonlinear differential equations in nodal coordinates of electromechanical state of power supply node of actuating induction motors with squirrel-cage rotors and massive hollow ferromagnetic and nonmagnetic rotors as element of control system is proposed; - the method of accounting of instant distribution of commutational currents in magnetic windings of elements of power supply node of actuating induction motors which is based on the power keeping law is elaborated. Methods of investigation and apparatus- the methods of solving of nonlinear differential equations with mixed ordinary and partial derivatives, the metods of solving of nonlinear algebraic equations. Practical results and novelty- the created computer programs of calculation of electromechanic transient processes of power supply node of actuating induction motors with squirrel-cage rotors and massive hollow ferromagnetic and nonmagnetic rotors from the supply node with comeasured power can be used for analisys of created control systems, and in the process of designing new systems. Object and degree of introduction- the results of the work is used in designing of control systems of electric drive of radio-radar antenna in Lviv Scientific-investigatonal Radioengineering institute, city Lviv. Effectiveness of introduction- by using of methods of calculation of commutational and transient processes of power supply node of actuating motors the optimal parameters of the cotrol system of electric drive of radio-radar antenna and optimal f orm of control sygnals are obtained. Sphere (branch) of using- producting companies and organisations engaged in design and producting of control systems.
