A comparative study of performance of AC and DC electric drive control systems with variable moment of inertia

In electric drive control systems, the main goal is to maintain driving motor speed meet mechanism’s requirements. some practical industrial applications mechanically-coupled load shaft has a varying mass during system operation. Therefore, change of changes value moment inertia system. The impacts operation, particularly transient performance. variation on its operation creates additional challenges accomplish high-quality control. purpose current work study impact performance both AC and DC systems make comparison between them. A mathematical analysis simulations models had been presented; one time with three-phase induction another motor, variable inertia. simulation accomplished using Simulink software in MATLAB. results these have analysed order get useful conclusions recommendations for designer.
