Nowadays, a current controller in a structure vibration, mostly in building is always focused on the velocities or full state feedback strategies. In fact, efficiency and accuracy is necessary needed such as a displacement and velocities of the structure are intricate to achieve straightly during the seismic activity. This phenomenon happen because the transducer used inside the controller are inexpensive and provided a reliable measurement of the structural accelerations. In this study, a new controller, Proportional Integral Derivative (PID) has been designed where it used to change the current state feedback controller. This PID controller is tuned using Ziegler-Nichols method. This method is used to tune the characteristic of the dynamics response of the controller. The PID controller had been tested using Quanser Active Mass Damper System (AMD) where AMD is a flexible structured that can swing without any friction. The Matlab SIMULINK has been used to create a simulation between the PID controller and the AMD. The result shows that the PID controller gives a good response to reject the disturbance produced by the structure vibration and it also able to absorb the vibration, respectively. Using the conventional controller, the value of phase margin, delay time and peak gain are 90.3 degree, 0.000381 second and 74.7 dB. But, using the PID controller there are 90 degree, 0.0000127 second and 75.6 dB for value of phase margin, delay time and peak gain, respectively. The result shows that the PID controller is more suitable to react with AMD to reduce the level of vibration.
