... using DOBC. Disturbance observers-based control techniques are fast and do not require the accurate model of the disturbance acting to execute motion control. The organization of the paper is as follows: First, the mathematical model of the spatial serial robotic manipulator is described, followed...

... voltage dynamic model is represented in symmetrical positive and negative sequence reference frames. A proportional controller structure with a first-order low-pass filter disturbance observer (DOB) is designed for power control in unbalanced voltage conditions. This controller is capable of meeting...
