Abstract

A simplified transfer function of PM synchronous servomotors is used to design various speed controllers: classic PI, H₂ and H_∞ ones. The controllers are tuned for the nominal plant, around which the mathematical model of the machine was linearised. The vector control-based driving system was simulated, imposing different perturbations: load steps, moment of inertia, friction coefficient. Robustness was analysed
