Control of Chua's Circuit with A Cubic Nonlinearity Via Nonlinear Linearization Technique

摘要

This paper addresses the controlling chaos problem of a cubic variant for the original Chua's circuit. A conventional input-output transfer function of a linearized system and a nonlinear linearization technique for a nonlinear system are also presented. According to analytical results, at equilibrium, the notion of local phase-minimality of the nonlinear system is equivalent to that of the linear system's transfer function. Or results also demon- strate that the controlled Chua's circuit, while considering a certain state as the system output, is an input -output linearizable minimum-phase system.
