Dynamic emulation of mechanical loads — position control approach

An approach to dynamic emulation of mechanical loads is presented, which can be used for the design and validation of variable position, speed and torque control algorithms. Actual mechanism is replaced by a dynamometer. Torque demand of the dynamometer is calculated from the closed-loop algorithm. Numerical model of the emulated load is used as a reference model and the impact of the test rig dynamics is compensated.
