Adaptive cradle for the neonatal growth

This paper deals with the LMS (Least-Mean-Square) method of adaptive adjustment technique to finish swinging amplitude and frequency control with tuning ability in swinging track control in a traditional structure of magnetic forced swinging cradle. Two forced patterns of one-side-push and higher frequency shaking are used to run different cases dynamically for a long-term period of natural swinging. With quiet and smooth swinging, the infants' brain can feel some changed phasic event in comfort when he or she is going to fall asleep. The two patterns combined adaptive control have the advantages of simplicity, variety and wider shaking frequency range. A well-controlled swinging pattern generator is provided for the clinical studies in the growth of babies and experimental data are collected to show the feasibility and good performance.
