Study on pid parameters tuning method based on Matlab/Simulink

Enormous calculation of proportional-integral-derivative (PID) controller parameters tuning with analytic methods is an important problem demanding prompt solution. Parameters tuning based on Matlab/Simulink is simplicity, visual manipulation method which leaves out above program. According to the Ziegler-Nichols (Z-N) method, this paper introduces how to reduce and validate the PID controller parameter with the help of MATLAB tool taking a certain control model as an example. The simulation results show the effectiveness of this method and can be fit for application in the engineering.
