Adaptive PID Speed Control Design for Permanent Magnet Synchronous Motor Drives

Jung, Jin-Woo; Leu, Viet Quoc; Do, Ton Duc; Kim, Eun-Kyung; Choi, Han Ho; Leu, Viet Quoc (2014)

This paper proposes an adaptive proportionalintegralderivative (PID) speed control scheme for permanent magnet synchronous motor (PMSM) drives. The proposed controller consists of three control terms: a decoupling ...
An Adaptive Voltage Control Strategy of Three- Phase Inverter for Standalone Distributed Generation Systems

Do, Ton Duc; Leu, Viet Quoc; Choi, Young-Sik; Choi, Han Ho; Jung, Jin-Woo (2012)

This paper proposes an adaptive control method of three-phase inverter for standalone distributed generation systems (DGSs). The proposed voltage controller includes two control terms: an adaptive compensating term and ...
A Nonlinear Sliding Mode Controller for IPMSM Drives with an Adaptive Gain Tuning Rule

Jung, Jin-Woo; Dang, Dong Quang; Vu, Nga Thi-Thuy; Justo, Jackson John; Do, Ton Duc; Choi, Han Ho; Kim, Tae Heoung (2015)

This paper presents a nonlinear sliding mode control (SMC) scheme with a variable damping ratio for interior permanent magnet synchronous motors (IPMSMs). First, a nonlinear sliding surface whose parameters change ...
Nonlinear Optimal DTC Design and Stability Analysis for Interior Permanent Magnet Synchronous Motor Drives

Do, Ton Duc; Choi, Han Ho; Jung, Jin-Woo (2015)

This paper presents a nonlinear optimal direct torque control (DTC) scheme of interior permanent magnet synchronous motors (IPMSMs) based on an offline approximation approach for electric vehicle (EV) applications. First, ...
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 ...
θ-D Approximation Technique for Nonlinear Optimal Speed Control Design of Surface-Mounted PMSM Drives

Do, Ton Duc; Choi, Han Ho; Jung, Jin-Woo (2015)

This paper proposes nonlinear optimal controller and observer schemes based on a θ-D approximation approach for surface-mounted permanent magnet synchronous motors (PMSMs). By applying the θ-D method in both the ...
