An integrated extended state observer (IESO) is proposed for smooth and fast speed control of dual three-phase permanent magnet synchronous machine (DTP-PMSM) drives in this article. The mechanical dynamics model of DTP-PMSM is established first based on the vector space decomposition (VSD) theory. The conventional extended state observer (CESO) and extended harmonic state observer (EHSO), which are capable of observing the lumped disturbance of the DTP-PMSM, are constructed on this basis. Then the transfer functions reflecting the tracking performance, disturbance rejection ability, and noise immunity property of the drive system are derived. The frequency characteristic analysis of the transfer function illustrates that the steady-state performance of EHSO is better than that of CESO, while the dynamic performance of CESO is better than that of EHSO. To possess all the aforementioned merits, an IESO integrating CESO and EHSO is proposed in this article, and the operating principle along with parameter design guidelines of the IESO are given. The feasibility and effectiveness of the proposed method are verified on a DTP-PMSM experimental platform.
