Implementation of EKF based sensorless drive system using vector controlled PMSM fed by a matrix converter

► We have designed an EKF based PMSM sensorless drive system fed by a matrix converter. ► Drive system combines advantages of matrix converter, PMSM and sensorless control. ► A low-cost TMS320F28335 floating point digital signal controller was used. ► A good performance is achievable at medium and high speed operations. ► A good performance of the drive system was illustrated by experimental results.
