| Abstract: | On the basis of the principle of angle digitalization of a synchronous electrical machine, the disadvantage of digitalization algorithm is pointed out. The present paper presents a new optimized algorithm based on the periodicity of angles, the limit of angles, and the tabulation space for software implementation. According to this new optimized algorithm, the angle signal can be digitalized by means of the hardware. The resolution of the antitangent function can be completed by means of the software technique, the digital representation of the angle is thus obtained. The experiments showed that the new optimized algorithm possesses the advantages of the software work being less, angle digitalization precision being high, calculating speed being rapid and the maintenance of the system being easy. |
