Dynamic emulation of mechanical loads — Analysis and implementation into industrial drive

The paper presents an approach to the dynamic emulation of mechanical loads. The main goal was to implement known control algorithm to the industrial converter SINAMICS S120 with the control unit CU320 using Drive Control Chart programming tool. The reference torque of a load machine is calculated through the closed-loop control algorithm using PI estimator. Proposed implementation enables the user the emulation of various mechanical loads with the industrial drive dynamometer, although only variation of the inertia and the viscous friction is reported here.
