Non‐invasive chaos control of DC–DC converter and its optimization

Abstract

Abstract The frequency‐domain‐based realization condition related to a novel non‐invasive chaos control is presented in this paper. According to the common piecewise‐linear characteristics of PWM‐controlled DC–DC converter system, a general expression for its Jacobian matrix is derived for optimizing the control parameters of the proposed non‐invasive chaos control. The relevant simulation and experiment results about the application of the chaos control to a voltage‐mode Buck converter are given, which confirm the feasibility of the parameter‐optimization method and the validity of the proposed non‐invasive chaos control.
