Hybrid Construction Machinery (HCM) differs from conventional Hybrid Electric Vehicles (HEV) by offering fuel consumption reduction not only in the traction system, but mainly in its hydraulic work implements. Regardless of the type of hybridization considered (series, parallel or series-parallel), Permanent Magnet Synchronous Machines (PMSM) are increasingly consolidating their position as the preferred option. Commercial motor drive systems usually can benefit of some revision in its control system and to take into account some of the specific needs of HCMs. This work revisit the PMSM drive control topic in face of the HCM requirements along with a method for controllers adjust, which is based in the disturbance-output relationship and makes use of feedforward and disturbance decoupling actions. Furthermore, it compares the proposed schemes with the ones used by some commercial products and shows how the they can improve the system disturbance rejection. Simulation and experimental results shows a better speed regulation with the proposed approach.
