Abstract

-This paper concerns the realization of a sensorless permanent magnet (PM) synchronous motor drive. Position and angular speed of the rotor are obtained through an extended Kaiman filter. The estimation algorithm does not require either the knowledge of the mechanical parameters or the initial rotor position overcoming two of the main drawbacks of other estimation techniques. The drive also incorporates a digital d-q current control which can be easily tuned with locked rotor. The experimental setup includes a PM synchronous motor a pulsewidth modulation voltage-source inverter and floating-point digital-signal-processor-based control system. Index Terms- Kaiman filtering permanent magnet synchronous motor sensorless drives.
