Some industrial drivetrain systems suffer from rotational speed ripples. Positive displacement compressor drives are a particular application in which the aforementioned problem arises, due to their non-constant angle-dependent load torque characteristic. The disadvantages of the induced torsional vibrations lead to the development of active control measures on the drivetrain’s prime mover to compensate for the load machine’s dynamic torque. The fundamentals of classical mechanics and electromagnetism are used, together with torsional vibration analyses and motor parameter identification tests, to build up a model of the experimental drivetrain. Active speed ripple suppression control strategies are in a second stage investigated and analysed, based on the characteristics of the dynamic load torque. The field-oriented control, resonant control, and iterative learning control are eventually the control strategies of interest, which are evaluated on both a simulation and experimental level. In the end, a comprehension is acquired around the advantages and inconveniences of the aforementioned control strategies on their speed ripple suppression performance.
