摘 要:本文主要介绍了一种电动舵机位置伺服控制系统优化控制策略。首先借助无刷直流电机固有的转子位置传感器对电位器检测信号进行补偿,针对舵面位置反馈提出了一种补偿方法。该方法能有效减小外界噪声信号的干扰,提高系统的控制精度。另外,提出了复合控制算法,同传统的PID控制算法相比,该算法在动态性能和稳态精度方面都具有明显优势。仿真结果表明,该控制策略响应速度快、超调量小,稳态精度高,能够有效抑制外界噪声的干扰,具有较好的控制精度和鲁棒性。 关键词:BLDCM;位置反馈;模糊PID控制; BangBang控制;复合控制
Abstract: 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.
