Aim at the characteristics such as nonlinear and inaccurate model, as well as the performance requirements of the valve controlled asymmetrical cylinder, the fuzzy adaptive PID control algorithm was proposed in this paper, which was based on the traditional PID control and fuzzy control theory. The controller has better control performance. The dynamic simulation result under MATLAB showed that the performance of this fuzzy adaptive PID controller has a higher stable precision, better robustness and faster response. It also suggested that this algorithm was valid for the valve controlled asymmetrical cylinder and provided theoretical and experimental basis.
