“…Moreover, the environment conditions of the human GI tract such as its Fluidic medium and the closed forms of the patient body are not taken into consideration in the performance evaluation of the proposed capsule guiding system. A new prototype of hand-held magnetic actuator is fabricated by Sun and co-workers [8] for a spiral-type WCE. The proposed actuator mainly consists of an external permanent magnet attached to a step motor used to guide a dummy capsule provided by a cylindrical magnetic shell and a spiral.…”

Wireless Capsule Endoscope (WCE) is a new medical device that can be used for examining the whole digestive tract if effectively actuated. In this paper, a new three-coil actuator is proposed for the capsule endoscope navigation system. The proposed system, which is based on the currentcontrolled magnetic levitation concept, utilises a small permanent magnet within the capsule body and an arrangement of controlled electromagnet actuator placed on a movable frame. The dynamics of the proposed control system is modelled mathematically and then formulated in state space form. In this research, the Linear Quadratic Regulator (LQR) technique is used for designing a 3DOF controller for the capsule actuation system. Artificial Bee Colony (ABC) tuning algorithm is used for obtaining optimum values for controller gain parameters. The optimised LQR controller is simulated by using the Matlab/Simulink tool, and its performance is then evaluated based on the stability and control effort parameters to validate the proposed system. Finally, the simulation results suggest that the LQR controller based on the ABC optimisation method can be adopted to synthesise an effective capsule actuation system.
