Design method for marine direct drive volume control ahead actuator

  •   Objectives   In order to reduce the size, weight and auxiliary system configuration of marine ahead actuators, this paper proposes a kind of direct drive volume control electro-hydraulic servo ahead actuator.
      Methods  The protruding and indenting control of the servo oil cylinder are realized through the forward and reverse of the bidirectional working gear pump, and the flow matching valve implements the self-locking of the ahead actuator in the target position. The mathematical model of the ahead actuator is established, and an integral separation fuzzy PID controller designed. On this basis, using AMESim software to build a simulation model of the ahead actuator, and combined with testing, this paper completes an analysis of the control strategy research and dynamic and static performance of the ahead actuator.
      Results   The experimental results agree well with the simulation results and verify the feasibility of the ahead actuator's design.
      Conclusions   The research results of this paper can provide valuable references for the integration and miniaturization design of marine ahead actuators.
