Improvement of Fuzzy PID Algorithm Based on Variable Domain Theory

In order to further improve the response speed and stability of the traditional PID algorithm to the cradle head, a variable domain theory fuzzy PID control algorithm is proposed in this paper to realize the dynamic characteristic control during the leveling process of the cradle head, and this algorithm is used to control the cradle head in the system. Matlab / Simulink tool was used for simulation experiment and analysis, and its expansion factor was studied. Finally, the advantages and disadvantages of it and traditional PID control algorithm were expounded systematically. The results show that compared with the traditional algorithm, this algorithm greatly improves the response speed of the platform, so as to meet the requirements of high speed response, dynamic stability, positioning accuracy and other capabilities of the cradle head to a certain extent.
