This paper proposes a new hybrid controller based on combining the ANFIS method and PID controller, for vibration mitigation of structural system. The proposed controller although has the PID controller features, create a fuzzy inference system that has fewer bugs and errors than neural networks in calculations. The whale optimization algorithm is used for optimum tuning the PID parameters and also for identification of parameters related to the experimental structure. Considering four well-known earthquake real data (ground acceleration) namely, El Centro 1940, Northridge 1994, Athens 1999 and Mexico City 1999, the performance of the proposed controller is evaluated. Then the results are compared with two other controllers namely, fuzzy logic control and ANFIS, which are designed for a four-degree of freedom building which is equipped with active tuned mass damper (ATMD). The simulation results show that the proposed method which is a combination of two controllers namely, ANFIS and PID, performs better than other strategies with are developed. The results obtained from the simulation show the better performance of the proposed method than the other control methods in reducing the structural responses in terms of displacement and acceleration of all floors. The results show that the maximum acceleration related to the building’s floors while using proposed method has improvement of 36.3% for the El Centro, 35.4% for the Northridge, 27.7% for the Athens and 22.5% for the Mexico City earthquakes regarding two other common controllers namely, fuzzy control and ANFIS control.
