| 摘要: |
| 为提高对超磁致伸缩作动器的控制精度,在基于Preisach模型前馈补偿的PID控制基础上,提出了一种基于Preisach模型前馈补偿的模糊PID控制方法．采用dSpace实时仿真系统搭建超磁致伸缩作动器的实时控制实验平台．利用研制的超磁致伸缩作动器测试了基于Preisach模型前馈补偿的模糊PID控制与PID控制方法下对方波信号和混合信号的轨迹追踪能力．两种控制方法下的实时控制效果对比分析表明,基于Preisach模型前馈补偿的模糊PID控制比常规PID控制具有更好的控制效果,从而验证了该方法的有效性． |

| Abstract: |
| To improve control accuracy for the Giant Magnetostrictive Actuator (GMA), the fuzzy PID control method is proposed by the PID control method based on Preisach model. The dSpace real-time simulation system is used to build the real-time control experimental platform of GMA. The designed GMA tests for the PID control method based on the Preisach model and the fuzzy PID control method in the square-wave signal and mixed-signal tracking were carried out. The effect of real-time control of two control methods was compared and analyzed, and the results show that the fuzzy PID control method is better than PID control method. |
