A typical control structure for an electrical drive system is depicted in Fig. 2. With respect to the achievable control performance, it has been proven to be advantageous to control the IPMSM in rotor-fixed coordinates. The crucial components in this context are the current controllers, which guarantee that the actual (measured) currents in the motor follow their reference provided by the operating point selection block. The design of the controllers can be performed in various ways, strongly depending on the required dynamics, robustness and available computation power. In this context, precise machine models, which account for varying inductivities due to iron saturation, can be utilized in the control design to improve the overall control performance. Therefore, LEA developed a semi-automatic method to generate motor specific LUTs through offline measurements. A further challenge lies in the rather small number of sampling instants per electrical rotation, especially at high motor velocities. In this context, advanced model discretization techniques, <del cite="mailto:DEFIGGH" datetime="2011-08-11T14:19"> </del>along with measures such as regular sampling become crucial to maintain a good control performance.
