• "Design, analysis, and control of a hybrid field-controlled axial-flux permanent-magnet motor"

Aydin M, Huang SR, Lipo TA, IEEE Transactions on Industrial Electronics 57 (1): 78-87 Jan 2010. This paper presents the design, analysis, control, and experimental evaluation of an innovative field-controlled axial-flux surface-mounted permanent-magnet machine.

• "Observer-based control methods for combined source-voltage harmonics and unbalance disturbances in PWM voltage-source converters "

Lee K, Jahns TM, Lipo TA, et al., IEEE Transactions on Industry Applications 45 (6): 2010-2021 Nov-Dec 2009. In this paper, computationally efficient sinusoidal-disturbance estimation and elimination methods are introduced into the control of an active front end (AFE) voltage-source converter (VSC) to achieve effective disturbance rejection in high power systems with slower pulsewidth-modulation switching frequencies (e.g., 5 kHz) and limited current-controller bandwidth.

• "Optimized design of stationary frame three phase AC current regulators"

Holmes DG, Lipo TA, McGrath BP, et al., IEEE Transactions on Power Electronics 24 (11): 2417-2426 Nov 2009. This paper presents an analytical method to determine the best possible gains that can be achieved for any class of practical linear ac current controller.

• "Modeling the 3-D rotational and translational motion of a Halbach Rotor above a split-sheet guideway"

Bird J, Lipo TA, IEEE Transactions on Magnetics 45 (9): 3233-3242 Sep 2009. The Halbach rotor is modeled using a 3-D analytic based model and is coupled to the conductive guideway region using boundary conditions. The steady-state rotation of the Halbach rotor is modeled by incorporating complex terms in the analytic model.
