英文摘要
      A set of two rings, levitated by electromagnetic means, is required to act as a leader-follower system in the smooth reference trajectory tracking task ascribed to the leader ring. The problem is approached from the perspective of active disturbance rejection control (ADRC) which entitles on-line disturbance estimation followed by controlled canceling. The main departure from traditional ADRC is based on the fact that tracking controllers of, both, the leader and the follower are designed on the basis of flatness combined with the tangent linearization of the corresponding nonlinear system around a constant equilibrium point. The large height deviations, outside the region of validity of the approximate linearization, trigger the effect of unknown (endogenous) nonlinearities viewed as perturbations. These disturbances are properly on-line estimated with the help of linear extended observers feeding a canceling effort on the individual linear output feedback controllers. Experimental results are presented which validate the effectiveness of the proposed control scheme.
