Sensorless Field Oriented Control Of Permanent Magnet Synchronous Motor Using Robust Hysterisis Current Controller With Rotor Position Tracking Pi Controller

This paper describes a sensorless field oriented control of permanent magnet synchronous motor (PMSM) using rotor position tracking proportional-integral (PI) controller. With the advent of vector control methods, Permanent magnet synchronous motor (PMSM) can be operated like separately excited dc motor for high performance application. This technique can be applied to low and high speed operations. In this method a loop recovery technique is applied, to boost the bandwidth of PI controller.. The design, analysis, simulation of sensorless method is done using MATLAB R2011a.
