Abstract: The electrolytic process of graphene preparation is nonlinear and uncertain. Using the traditional proportional integration differentiation (PID) control algorithm is difficult to accurately control the electrolytic current and electrolyte ion concentration in the preparation process, resulting in the problems of uneven agglomeration and stripping in the process of graphene preparation by electrolysis, Accordingly, an adaptive fuzzy PID algorithm is designed and the corresponding mathematical model is established. The process accuracy of graphene preparation can be better controlled by using the model. The comparative simulation of adaptive fuzzy PID algorithm and traditional PID algorithm is carried out with MATLAB, and the simulation results are analyzed and discussed. The adaptive fuzzy PID algorithm is better in the performs of response time, anti-interference ability and stability, and more in line with the requirements of graphene preparation control system than the traditional PID algorithm.
