It is shown that two-component Wadati-Konno-Ichikawa equation, i.e. a generalization of the wellknown WKI equation is obtained from the motion of space curves in Euclidean geometry, and it is exactly a system for the graph of the curves when the curve motion is governed by the two-component modified Korteweg-de Vries flow.

This invention concerns a current control process for a feed-in voltage converter, wherein a detected flux-inducing current component and a detected torque-inducing currrent component of an actual currrent vector of a rotating field machine are each controlled for a flux-inducing current component set value and a torque-inducing current component set value of the rotating field machine. To that effect, a control set-value (DELTA u*sp, DELTA u*sq) is determined, dependent each time upon a determined current component control deviation. From these, current components of an actual current vector are formed each time by overlay of a formed pilot value (u*spvor, u*sqvor). This invention also concerns a device for carrying out this process.

The first one is to generate the circle for each borderline segment of the component by considering the segment length and the prescribed tolerance value. If this is not the case, the borderline segment will be equally divided into halves until the obtained circle satisfies the tolerance value over the whole borderlines of the component. The basic idea of the last two algorithms aims at covering the domain occupied by the component as much as possible. The circle generation is carried out sequentially from salient angle to the sector formed by the salient angle till the uncovered borderline segments of the component. Particularly, the three-step algorithm with gap allows that the generated circles are distributed with gap along the component contour.
