Abstract:

In order to make the platform respond quickly to environmental changes so as to achieve dynamic balance, a variable domain theory fuzzy PID control algorithm is proposed to realize dynamic characteristic control design in leveling process. The system takes ARM920T as the control unit, and uses the fuzzy PID algorithm to control the platform. The simulation analysis of the fuzzy PID algorithm is carried out by using MATLAB. Finally, the effects of variable universe, fuzzy and traditional algorithms are compared. On the premise of guaranteeing dynamic stability, the fuzzy PID algorithm can effectively improve the response speed compared with the conventional PID algorithm.
