In the field of permanent magnet synchronous motor (PMSM) self-sensing control, the initial rotor position estimation is always important, for which the rotor magnetic polarity estimation is particularly a major task. This paper presents a robust rotor polarity estimation method based on the comprehensive utility of both magnetic saturation effect and rotor angular acceleration. The method can be...

Traditionally embedding parameters: embedding dimension m and delay time τ are determined separately in state space reconstruction of chaotic dynamical systems. While recently some researchers argued that delay time window τw = (m-1)τ should be determined first. In this paper we carry out a contrast test and come to a conclusion that m rather than τw is more crucial for the quality of reconstruction...
