The TDFC method for control unstable chaotic behaviour in boost converter

摘要

A control and stabilizing approach for chaotic behavior of converter is introduced in this paper for the removal of harmonic caused by chaotic behavior in current converter. For this work, a TDFC control Method for stability chaotic behavior of boost converter for switching courses in current control mode is presented. For analyze equations in converter the behavior converter presents by discrete equations. This behavior is demonstrated by presenting a piecewise linear discrete map for this converter and then combining the feedback equation (that is contain current control equation and Time delay feedback control equation) to obtain the overall equation of the converter. A simple time-delay feedback control method is applied to stabilize the unstable periodic orbits (UPOs). By using the time-delayed feedback control method, the stability limit and gain range of the system are increased.
