A Generalized Observer for Estimating Fast–Varying Disturbances

Ton, Duc Do; Nguyen, Hoach The (IEEE, 2018-04)

In this paper, a generalized disturbance observer (GDO) is proposed for estimating a broad range of disturbances including fast-varying ones. The estimation error of the proposed GDO is proven to be ultimately bounded ...
SDRE-Based Near Optimal Control System Design for PM Synchronous Motor

Do, Ton Duc; Choi, Han Ho; Jung, Jin-Woo (IEEE, 2011)

This paper presents a nonlinear optimal speed controller based on a state-dependent Riccati equation (SDRE) for permanent magnet synchronous motor (PMSM). An SDREbased near optimal load torque observer is also proposed ...
