The Design and Implementation of Control and Driving system with Double Position Feedback for Submarine Steering

Abstract

With the well improvement of motor and power electronic technology, the technology of Electro-mechanical actuator (EMA)has come into a new stage. A high-reliability driving and controlling technology with a double redundancy feedback loop is described in this paper. In this method, the position of electromechanical actuator and the resolver position of motor can be back up for each other by some compensate algorithms. This method can improve the reliability of the control system without extra hardware and increasing cost.
