Abstract
In the present study, a simulation driven PID controller gain estimation methodology is proposed. For simplicity, a cantilever beam is used as a dynamic system and it is excited by using an unbalanced oscillating mass. The vibration is measured with the help of patch type piezoelectric vibration sensor. To provide the actuating force at the free end of the cantilever beam, a rack and pinion type actuator is designed and developed. First the modal parameters are evaluated and subsequently state space model is developed. The initial values of PID gains are estimated using state space and feedback controller designed on Simulink software. The initial gain values are tuned according to physical cantilever beam system. Finally, the vibration results are compared for with and without active vibration control methods as well as before and after the PID gain tuning. The results show that the use of proposed methodology to control the vibration actively using a simulation driven designed PID controller is effective and less time consuming as it gives initial guess of PID gain values.
