Abstract
This paper focuses on designing a disturbance observer-based control (DOBC) system for
PMSM drives. The cascade structure of the discrete-time PI-PI control system with tracking anti-windup
scheme has been designed for both loops. In this study, high order disturbance observer (HODO) based
control is used to improve the speed tracking performance of the control system for the PMSM prototyping
kit regardless of the disturbance and unmodelled dynamics. The motion equation was modified in the HODO
in which torque losses due to the drug resulting from the time-varying flux, hysteresis, and friction have
been taken into account to estimate the total disturbance. The HODO does not require the derivatives of
the disturbance to be zero, like in the traditional ones. It demonstrates its ability to estimate along with a
load torque the high order disturbances caused by a cogging torque and a high-frequency electromagnetic
noise in the PMSM system. In the real-time experiments, the proposed algorithm with HODO achieves less
speed errors and faster response comparing with the baseline controller. The performances with proposed
and baseline control have been evaluated under mechanical speed and load torque variation cases. The
experimental results have proved the feasibility of the proposed control scheme. The proposed disturbance
observer-based control system was implemented with a Lucas-Nuelle 300 W PMSM prototyping kit.
