Ravish H. HIRPARA State Estimation of Permanent Magnet Synchronous Motor Dynamics Using Higher-order Continuous-Discrete Filtering Equations
ABSTRACT: In electrical machine theory the permanent magnet synchronous motor (PMSM) dynamics has been studied extensively. In this paper we have derived filtering equations of PMSM dynamics using higher-order continuous-discrete filter and simulated these equations with two sets of initial values. In this paper process noise is involved with continuous state dynamics of the PMSM and that is coupled with discrete measurement equation, which is involved with discrete measurement noise. Notably, the filtering equations of this paper explicit contribution of the predicted estimate and the observation noise to filtered estimate. The filtering theory presented in this paper will be useful to applied mathematicians, Control engineers for better understanding of the continuous-discrete filtering equation of the non-linear dynamics. Especially for stochastic problems arising from intelligent industrial systems.KEYWORDS: Continuous-discrete filtering equations; non-linear filtering; PMSM dynamics; stochastic differential equations; stochastic systemsRead full text (pdf)
