What is it about?
Aimed the PMSM sensorless control problems of the EPS system in this paper, a PMSM discrete mathematical model is established using the Euler method, and an iterative fifth-order CKF algorithm is applied to the PMSM speed estimation.

Why is it important?
For the PMSM, the rotor position and speed signal are essential for good control. Currently, the acquisition of the rotor position signal has mainly been achieved by installing a photoelectric encoder or rotary transformer. However, this will not only increase the cost but also reduce the reliability of the system. To solve this problem, the PMSM sensorless technology have been studied.
