Abstract：To eliminate position-dependent disturbances in a constant-speed-rotation system,we have proposed a very effective approach that introduces a new concept called the"position domain".However,because the position domain model of a linear plant is in fact nonlinear,a linear control strategy may not meet the design requirements.To solve this problem,this paper proposes a nonlinear repetitive control approach.The procedure for designing a control system comprises two steps.First,an input-output linearization approach is used to linearize the input-output characteristics of the nonlinear plant in the position domain.Then,a repetitive controller is designed for the linearized plant to ensure good performance.
