This paper presents an observer-based approach to the determination of environment forces acting on a rigid body. Actuation forces, measured p ositions and orientations and identiication 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(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)
