LIU, K. and ZHU, Z.Q., 2015. Position-offset-based parameter estimation using the adaline NN for condition monitoring of permanent-magnet synchronous machines. IEEE Transactions on Industrial Electronics, 62(4), pp. 2372-2383.
This paper proposes how to use the addition
of rotor position offsets as perturbation signals for the parameter estimation of permanent-magnet synchronous machines (PMSMs), which can be used for the condition
monitoring of rotor permanent magnet and stator winding. During the proposed estimation, two small position offsets are intentionally added into the drive system, and the resulting voltage variation will be recorded for the estimation of rotor flux linkage. With the aid from estimated rotor flux linkage, the stator winding resistance can be subsequently estimated at steady state. This method is experimentally verified on two prototype PMSMs (150 W and 3 kW, respectively) and shows good performance in monitoring the variation of rotor flux linkage and winding resistance.
