Abstract:

The traditional PID regulator can get a satisfactory control effect in many situations. But because of the welded pipe servo cutting system characteristics with not fixed the parameter, variable, strong nonlinear and coupling complex, it is difficult to obtain ideal response in different time, and it is also hard to adapt changes in the environment and the uncertainty of the system. In allusion to the defect of the traditional PID regulator in the welded pipe cutting machine, it is put forward the parameter self-setting fuzzy PID adjustment method and a kind of fuzzy reasoning control rule in this paper. According to the rule, a welded pipe cutting machine control system mathematical model is established and numerical simulation of tailing after the given order jump curve in adaptive fuzzy PID regulator is finished. The simulation results show that: the system response speed is faster than before, the system adjusting precision and stability become well. All of this is hard to realize from traditional PID.
