Research on Synchronous Control Method for Dual-Cylinder Propulsion Based Marine Electric Steering Engine

A double AC synchronous servo motor control method for marine electric steering engine is proposed to improve the low accuracy of hydraulic servo system. In this structure, an implementing consistency control mode is present as well. Finally, by building a principle prototype system, the accuracy and validity of control method is verified. The results show that the dual cylinder synchronous operation method and its consistency control mode is satisfied.
