This paper presents an observer-based approach to the determination of environment forces acting on a rigid body. Actuation forces, measured positions and orientations and identi cation of inertial parameters are used for this purpose. It is also shown that environment force estimates can be used in turn to correct rigid-body velocity estimates generated by(More)
The flicker and harmonics generated by electric arc furnaces present a problem that is well known to both the steel industry and electrical utilities. This paper presents a method to compensate for measurement errors introduced by current and voltage transformers and anti-aliasing filters in a power quality measurement system. Dynamic compensation may be(More)
