Magnetic levitation system에 대한 control demo 입니다. attractive magnetic force를 이용하는 형태입니다. LW-RCP unit와 Simulink를 이용하여 제어하였습니다. 동작점 기준으로 선형화하였고, Luenberger observer와 pole placement를 결합한 구조입니다. 부양체로 사용하는 음료수 병의 뚜껑에 네오디뮴 자석을 강력 접착제로 붙여 전자석에 의한 인력을 강화하였습니다.

This video shows the control demonstration of a magnetic levitation system. It utilizes the attractive magnetic force for control. We used LW-RCP unit (developed by SungJin Techwin) and Simulink for real-time control. We used a linearized model for controller design. Luenberger observer was used for state estimation and pole placement for state-feedback gain. A Neodymium magnet is attached to the lid of the beverage bottle used as a levitated object with strong adhesive to strengthen the attractive force of electromagnets.
