A Design of Optimal Controller with Friction Reduction of Linear Motor-based Transfer Technology via Lift-force Control

부상력을 이용한 LMTT(Linear Motor-based Transfer Technology) 의 마찰력 감소에 대한 최적 제어기 설계

The existing automation transfer systems such as AGV(Automated Guided Vehicle) have many problems (maintenance, accuracy, velocity, etc.) and wastes of a vast space and time. Hence we have suggested to LMTT(Linear Motor-based Transfer Technology). This paper deals with fundamental LMTT, and proposes a concept of mass reduction and propulsion control for LMTT when it is starting and reaching an object by using lift-force. By applying optimal controller and the repulsive lift forte in the LMTT, a large percent of vehicle weight is compensated and it reduces friction, then it needs less thrust force to propel the vehicle.
