For non-contact drive of capsule micro robot in bending intestine, we propose a technical scheme in which three axis orthogonal square Helmholtz coils are employed to generate a spatial universal outer rotating uniform magnetic field using magnetic field superposition principle. For their optimization design, electromagnetic mathematical model of the three(More)
This paper is concerned with uncertain systems subject to periodic disturbances with a known period, and the discrete-time variable structure repetitive control methodology is applied to address the control problem. The notion of quasisliding mode is reviewed in this paper. Switching-function dynamics obtained with the proposed repetitive strategies are(More)
