Stabilization of Chaos with Fpic: Application to Zad-strategy Buck Converters
نویسندگان
چکیده
In this paper a new design for controlling dynamical systems has been applied to buck converters driven with a PWM centered pulse and (Zero Average Dynamics) ZAD-strategy. Chaotic operation has been stabilized with the so-called Fixed Point Induced Control (FPIC) technique. Also, the same converter with delay, whose 1-periodic orbit is always unstable, has been stabilized. Simulations are compared with the TDAS stabilization technique. Once a 1-periodic orbit has been stabilized, the dynamics shows the same characteristics and advantages of the ZAD design, such as robustness, fixed switching frequency (with zero average on the sliding surface) and a low output error.

Effects of quantization, Delay and Internal Resistances in Digitally ZAD-Controlled buck converter
Zero Average Dynamics (ZAD) strategy has been reported in the last decade as an alternative control technique for power converters, and a lot of work has been devoted to analyze it. From a theoretical point of view, this technique has the advantage that it guarantees fixed switching frequency, low output error and robustness, however, no high correspondence between numerical and experimental re...
متن کاملTwo-Parameter bifurcation Curves in Power Electronic converters
In many control problems, the control strategy is phrased in terms of average quantities. In this paper we prove the general result that, given a linear system ẋ = Ax + u where A is hyperbolic, u is piecewise linear and L-periodic, such that R L 0 u(t)dt = 0, then there exists a unique Lperiodic solution x = xp(t) such that R L 0 xp(t)dt = 0. We then consider a DC/DC buck (step-down) converter ...
متن کاملQuantization Effects on Period Doubling Route to Chaos in a ZAD-Controlled Buck Converter
The quantization effect in transitions to chaos and periodic orbits is analyzed in this paper through a specific application, the zero-average-dynamicsZADcontrolled buck power converter. Several papers have studied the quantization effects in the one periodic orbit and some authors have given guidelines to design digitally controlled power converter avoiding limit cycles. On the other hand many...
متن کاملTransition from Periodicity to Chaos in a PWM-Controlled buck converter with Zad Strategy
The transition from periodicity to chaos in a DC-DC Buck power converter is studied in this paper. The converter is controlled through a direct Pulse Width Modulation (PWM) in order to regulate the error dynamics at zero. Results show robustness with low output error and a fixed switching frequency. Furthermore, some rich dynamics appear as the constant associated with the first order error dyn...
متن کاملPassivity-Based Control of the DC-DC Buck Converters in High-Power Applications
In this paper, a novel approach for control of the DC-DC buck converter in high-power and low-voltage applications is proposed. Designed method is developed according to passivity based controller which is able to stabilize output voltage in a wide range of operation. It is clear that in high-power applications, parasitic elements of the converter may become comparable with load value and hence...
