Kontrol PID Untuk Pengaturan Kecepatan Motor Pada Prototype Ayunan Bayi Otomatis

In the globalization era like today, to meet the necessities of life required hard work. Therefore, everyone is very busy with their jobs, let alone living in a metropolitan city certainly has a style of life that wants everything completely automated, rapid and practical. For parents who have newborn babies usually at night while asleep, they were disturbed by a crying baby and had to calm him down. Most babies wake up in the middle of the night because sleep phase changes from deep sleep to light sleep and then wake up. When the baby wakes up usually will cry and usually mothers breastfeed or hold her baby. To solve the problem then created a system that can swing the baby to the left and right like a pendulum with a speed that is regulated by PID control to obtain stable swing. Tuning PID parameters obtained with the reaction curve method. Additional facilities are provided by the electoral system level speed adjustable via pushbutton and a baby crying detection using a condenser mic. The results obtained after testing on PID controller, amplifiers, frequency detector and the time of execution stated that the system has 87% accuracy.
