中文摘要:

      为了提高舵系统可靠性，采用了冗余策略，设计了双余度舵系统。选用双余度永磁无刷直流电机作为舵机本体，采用均流技术等控制策略，实现系统软硬件设计。利用Matlab/Simulink，对双余度无刷直流电机本体和舵系统整体进行仿真验证。仿真结果和实验结果表明，该设计实现了对角度的高精度跟踪，整个系统稳态误差小、性能优良。

英文摘要:

      In order to improve the reliability of the rudder system,redundancy strategy is introduced.Using dual-redundancy brushless DC motor(BLDCM) and balanced current strategy,hardware and software of dual-redundancy rudder system are designed.The simulations of dual-redundancy BLDCM and rudder system are given.The simulations and experimental results show that this design achieves a high precision tracking for angle,the steady-state error of this system is small,the performance of this system is perfect.
