Modeling of Flatness-Based Control with Disturbance Observer-Based Parameter Estimation for PMSM Drive
Authors: , , , , , , ,
Abstract: This paper presents a modeling of nonlinear control with parameters identification for the permanent magnet synchronous motor (PMSM) drive. A resistance in series with an inductance and the conduction losses in semiconductor switching devices of inverters represented by vtq (=Rs*iq) as well as the torque load TL are going to be estimated by observer method based on extended Luenberger observer (LOB). The simulation and experimental results show the proposed control provides the rapid response and flat of the current control loop for the PMSM drive system. Moreover, the observer approach precisely estimates both vtq and TL, and the converging time is less than 0.1 sec. The test bench was implemented by small-scale PMSM 1 kW, 3,500 rpm, 6 ampere rated to validate the proposed control approach.
