基于模糊PID控制的经纬仪直流伺服系统仿真研究

天文经纬仪位置随动伺服系统对于星体的检测具有重大的影响。以天文经纬仪位置随动系统为控制对象，针对该系统的非线性、参数不确定性及对实时性和无超调的要求，将传统的PID控制算法与模糊控制算法相结合，提出了在线模糊自调整PID控制方法，并在simulink环境下进行了仿真，仿真及实验结果表明，该算法具有良好的稳态精度和动态响应速度。

Simulation of DC Servo System of Transit Instrument Controlled by Fuzzy-PID

The servo system is a very important part of celestial transit instrument, it exert a vital effect on the detection of star. For the system, it has a non-linearity feature and uncertainty of parameters, and it should require a real-time operation and non-overshoot. In this paper, we discuss the application of fuzzy logic control in DC servo system, aiming at the defects of PID controller in overshoot and response speed, On the basis of this study, we put forward the fuzzy-PID controller, and apply the method of checking form to increase its response time. Simulation results demonstrate its advantages in robustness and the adaptability.
