Abstract:Basis weight control system in paper manufacturing process is a high order non-linear system with time delay and complicated interference. According to the characteristics of basis weight control system, this paper proposed a PSO-PID parameters tuning method based on H∞ optimal control theory. By introducing the liner decreasing inertia weight ω to optimize the PSO′s global and local searching ability. Simulation results verified that the proposed strategy could find a group of PID tuning parameters efficiently, thereby reducing the searching scope. Furthermore, compared to conventional PID parameter tuning methods, this strategy had a better convergence rate and computation precision; robustness and response speed of the system were improved as well.
