A new ball and beam system using magnetic suspension actuator

This paper presents a ball & beam system using a pair of magnetic suspension actuators by applying precision position control in performance. System characteristics including magnetic actuator, linear position sensor, load current control and feedback loop are discussed. To achieve the control, a single chip microprocessor with basic level electronics is designed and implemented. The designed system model is derived from Lagrangian function for system controller implementation. Oscillatory stable operation and sinusoidal tracking operation are tested to verify the system performance and functional capability.
