Study on Optimized Control Strategy of Rudder Servo System

In this paper,an optimized control strategy was introduced for a rudder servo control system.First,a compensation method was presented to orientate the position of rudder surface precisely with the help of rotor position sensor of BLDCM.The noise interference to the system could be suppressed effectively,and high control accuracy would be realized.In addition,put forward a compound control algorithm,and the dynamic performance and stable precision of the system were highly improved compared with traditional PID control.The simulation results also illustrate that excellent overshoot and response speed and high stable precision as well as good robustness can be obtained by the proposed strategy.
