Developing function diagram of digital-analogue control system of ship electric drive

The article considers the direct digital control based on microprocessor technology, which has both undoubted advantages in implementation and some difficulties, for example, work real time. When developing system, two main problems were taken into account: a compromise choosing possible equipment signal processing devices. A function diagram of digital-analogue system ship electric drive is proposed, with can help to increase reliability an variable speed. monitored regulated, current, voltage, rotation frequency, shaft angle are under control. In addition, functional frequency been developed, converted analog form using digital-to-analog converter. application two-phase sinusoidal generator voltage shaper proposed obtaining signals high stability phase displacement amplitude, important from point view energy characteristics drive. Further, converter used as reference that generates signals. After element base it be concluded read-only memory device programming carried out each engine separately, contrast rest circuit blocks, universal, creates difficulties creating universal There found possibility implementing current by rational distribution functions between
