Improved PID Controller for Suppression of Vibrations in Buildings
2020
Guarding buildings and residents against calamities caused by vibrations is very crucial. Active vibration control devices combined with control systems have shown fruitful results. The study was an effort to tackle the issue of complexity and improving robustness in previous control methods proposed by scholars. The modified PID controller combined active force control method was able to reduce the vibration of both levels of the building structure investigated by 99.99% and also the amount of control signal required was reduced to the minimum. The method maintains the advantages of the PID controller most especially simplicity as well as robustness of the active force control scheme. Hence, it might make a breakthrough in active vibration control in buildings as well as other similar structures, although further investigations may be required. The study is novel in the sense currently no such technique was proposed for eradication of vibration disturbances in buildings.
