Initial Rotor Position Detection of Induction Machines Using Feedforward Sensorless Saliency Separation

open access: yesPower Electronics and Drives, 2021
The use of induction machine spatial saliencies for sensorless vector control in the proximity of zero electrical frequency has been extensively researched over the last few decades. A robust technique to extract machine saliencies is called voltage step

A family of asymptotically stable control laws for flexible robots based on a passivity approach [PDF]

open access: yes, 1991
A general family of asymptotically stabilizing control laws is introduced for a class of nonlinear Hamiltonian systems. The inherent passivity property of this class of systems and the Passivity Theorem are used to show the closed-loop input/output ...

Linear motor motion control using a learning feedforward controller [PDF]

open access: yes, 1997
The design and realization of an online learning motion controller for a linear motor is presented, and its usefulness is evaluated. The controller consists of two components: (1) a model-based feedback component, and (2) a learning feedforward component.
