Structural Synthesis of a Dynamic System Control Algorithm Based on the Separation of Electromagnetic and Electromechanical Movements

A method for the synthesis of a dynamic system control algorithm based on structural synthesis of motion control systems is proposed. The technique allows, due to the separate assignment of the required movement of individual elements of the system, to extend known methods to dynamic systems, a characteristic feature of which is the impossibility of obtaining a mathematical model in the form of a single differential equation. These systems include the cascade frequency drive system. The results of applying the proposed methodology for the synthesis of an asynchronous electric drive control system are given. The synthesized system is characterized by aperiodicity of movement and provides astatic regulation with the stability of dynamic processes regardless of disturbing influences (frequency of stator voltage and drive load) in the absence of energy constraints on the control action.
