Using a decoupling technique to identify the magnetic flux in a permanent magnet synchronous motor

Unknown parameters cause difficulties in the control of permanent magnetic motors. Particular techniques are requested to be able to achieve an appropriately controlled dynamics identification. A geometric approach for achieving a decoupling of the system is applied in the presented strategy. The decoupling makes the estimation of the Permanent Magnet Synchronous Motor (PMSM) parameters easier. A feedback controller in combination with the feed-forward controller being generated by an input partition, achieves the decoupling. This can be applied to various types of motors or systems in case of the decoupling conditions being satisfied. A control together with the identification method is tested in the simulation section. The presented simulation and measured results are shown for validation of the strategy which is proposed.
