Recent development in brushless do motors and their drives provided the technology to build electromechanically actuated primary controls, hence they were proposed for pound, aerospace and (recently) mercantile applications. This paper addresses the transfer of single type summing architectures (namely, velocity, Torque and electromagnetic summing) to marine technology. The paper will highlight the drawbacks in such architectures and will propose (as an alternative) a novel Electromagnetic Torque Summing technique and will address the possible application of a vibration control method to this type of architecture. The previously proposed Fault detection and Fault Isolation system (in the all-electric aircraft) will be recommended and description of suitable threshold setting techniques on the imbedded Monitoring Devices will be given. The paper will also show how stringent space and response requirements in aircraft actuation systems could be relaxed when actuation technology is transferred to propel marine systems.
