摘要
为了提高系统结构特性改变之后系统对信号抑制的能力,抑制扰动信号对伺服系统输出的影响,本文提出一种对扰动信号进行模糊补偿控制的方法。其中模糊控制环节选用PID控制来进行参数整定,补偿系统对外加扰动产生的偏差,本文所设计的控制系统不需要在原系统上附加额外的传感器,因此不会增大系统的复杂度。本文运用频域分析的工具来设计PID控制器的参数,随后再以此为根据进而设计模糊控制器的规则。最后,再对这种控制系统进行了3个维度的仿真分析,从仿真结果得出:在快反镜的结构参数改变的前后,模糊补偿控制系统对系统的扰动信号的抑制能力是高效的。
In order to ensure the ability of the control system to suppress the disturbance signal after thechange of the system structure characteristic and to suppress the influence of the disturbance signal onthe output of the servo system, this paper proposes a method of fuzzy compensation for the disturbancesignal. The output parameters of the fuzzy control link are used to set the PID control parameters. Thecompensation system does not need to add additional sensors and will not increase the complexity of thesystem. In this paper, the frequency domain analysis tool is used to design the parameters of the PIDcontroller, and then the rules of the fuzzy controller are designed. Finally, the simulation analysis of thethree dimensions of the control system is carried out. From the simulation results, the fuzzy compensationcontrol system is efficient to the disturbance signal of the system before and after the change of thestructural parameters of the fast mirror.
