Abstract—The first order plus time delay (FOPTD) model was assumed and the improved relay tuning method was applied for tuning with higher order of relay harmonics. A relay feedback test was conducted to obtain a symmetric relay response and ultimate gain. Then Ziegler-Nichols optimum controller parameter method was applied for estimation of optimum control parameters for the given system. The Artificial Neural Network was applied to the closed loop model. It was found that the predicted model response was close to that of actual one.
