Control Realization for an Interior Permanent Magnet Synchronous Motor ( IPMSM ) in Automotive Drive Trains

The specific requirements for electrical automotive traction drives are a wide speed range, a wide constant-power operation range and high efficiency. In this paper a suitable control scheme is presented that ensures good dynamics, stability and high efficiency in the whole operation range. The focus is on the regular-sampled current control design, which requires a precise discrete-time model including the effect of a small number of sampling instants per electrical rotation. A suitable model as well as an adequate controller design is presented. The control is realized and evaluated by experimental results.
