In this paper we deal with the control of chaotic systems. Knowing that a chaotic attractor contains a myriad of unstable periodic orbits (UPO's), the aim of our work is to stabilize some of the UPO's buried in the chaotic attractor and which have interesting characteristics. First, using the input-to-state linearization method in conjunction with a time-delayed state feedback, we design a control...
This work deals with the behavior of the controlled two cell DC/DC converter. It has been reported in literature that the two-cell DC/DC converter may exhibit chaotic behavior under a badly tuned proportional controller. To stabilize the periodic orbit sank in the chaotic attractor we propose to apply the discrete time-delayed feedback controller. We first present conditions of stability using the...
In this work, we suggest a controller which is simple to construct to lead to zero current and zero voltage static error in the behavior of a two-cell dc/dc buck converter. Using nonlinear analysis we prove that zero error is achieved even in presence of duty cycle saturation.
In this paper we deal with the control of a two-cell DC/DC buck converter. The design is based on a discrete state space model obtained by expressing current and voltage at the beginning of the (n+1)th period in terms of values of the preceding period. It is shown that the describing model is nonlinear, therefore it is expected that a standard linear controller (e.g. PID) would not be efficient. In...
