The design method and application of one intelligent integrator

By analyzing linear integrator's characteristic and control performance requirement with intuition reasoning, it is indicated that nonlinear intelligent integrator must possess on-line learning and complete memory function. If the system has no errors at steady state, the amplitude of one-order harmonic of the intelligent integrator should be infinite when the frequency of integrator is zero. One intelligent integrator algorithm is provided. By one-order harmonic analysis, its phase Lag is between -57.6° and 45°. The simulation indicates the very good performance of the integrator.
