“…The PID control can be extended to Fractional Order PID (FOPID) control [5], then can optimize the parameters of the FOPID through particle swarm optimization algorithm, thereby improving current stability and suppressing harmonic interference. In [6] and [7] proposed a model reference and periodic adaptive learning control method based on the Lu-Gre friction model for friction compensation, thereby ensuring tracking performance. Model predictive control has been widely experimentally verified in motor control theory.…”

The azimuth axis drive and control of large telescopes based on Segmented Arc Permanent Magnet Synchronous Motor (SAPMSM) is a current research hotspot, and issues such as unknown parameters and external interference are important factors affecting its tracking accuracy. This paper proposes a SAPMSM perturbation suppression strategy for large telescopes based on port-controlled Hamiltonian (PCH) theory. In this study, the Hamiltonian mathematical model of SAPMSM is established and the current controller of the SAPMSM is designed to reduce harmonics by configuring the required interconnection and damping matrix. In order to further improve the accuracy and anti-disturbance performance of speed feedback, a Generalized Proportional Integral Observer (GPIO) is selected for total disturbance observation, estimation and compensation. The experimental results indicated that the algorithm proposed in this paper has lower harmonic content in the phase current of the SAPMSM, which can ensure good position tracking ability and anti-interference performance of large telescopes.INDEX TERMS Segmented Arc Permanent Magnet Synchronous Motor (SAPMSM), hamiltonian theory, large telescopes, Generalized Proportional Integral Observer (GPIO), anti-interference performance.

This paper studies the electromagnetic field used for driving a vibro-impact capsule prototype for small bowel endoscopy. Mathematical models of the electromagnetic field and the capsule system are introduced, and analytical solution of the magnetic force applied on the capsule is derived and verified by experiment. The impact force between the inner mass of the capsule and the capsule body is also compared via numerical simulation and experimental testing. By comparing the capsule’s progressions under different control parameters (e.g. the excitation frequency and duty cycle), the merits of using the vibro-impact propulsion are revealed. Based on the experimental results, the optimised speed of the prototype can achieve up to 3.85 mm/s. It is therefore that the potential feasibility of using the external electromagnetic field for propelling the vibro-impact capsule system is validated.
