Abstract

The design of Proportional-Integral-Derivative (PID) controller is involved to gain infinite stiffness using active vibration control system and it’s a modification of previous work. The PID controller is a control loop feedback mechanism which steadily calculates a fallacy value as the difference between a desired set point and a variable process and applies correction based on proportional, integral and derivative terms. In this paper to achieve infinite stiffness magnetic field has been created by passing current, the input of the electromagnet is the output voltage of the sensor. Depending upon the gap between electromagnet and suspended object vibration is isolated by the attractive force of the electromagnet. The control system is also implemented via analog control circuit and microcontroller to achieve infinite stiffness. When maximum force has been applied in this system there will be no deflection i.e. generalized force and deflection. This thesis paper also presents the application, limitation and scope of this system
