This paper proves that taking the inertia time constant as the parameter of the integration time(Ti=T)would make the system dy-namic performance optima when the delay time is less than or equal to the inertia time constant(τ≤T),on the other hand,it's bet-ter to choose the value between the inertia time constantand the delay time(T<Ti<τ)when the delay time is greater than the inte-gral(τ>T).It can summarize the parameter tuning rules and verify the effectiveness of the rules through the simulation.Finally,a parameter tuning method for τ>T and τ≤T,which emerges fast dynamic performance from results of the analysis and simulation and increase the maneuverability of the process.
