“…Control of DC-DC converters has been of particular interest in the last two decades [1]- [4]. From the control point of view, nearly all the power conversion systems are regarded as a tracking problem because the output quantity should follow the reference command with a fast transient behavior and a low steady-state error.…”

“…These approaches cannot normally guarantee an optimized large signal behavior, including the start-up regime. Even advanced linear control approaches, such as   [11]- [13], µ [14]- [17], and Hammerstein model-based control [3], [18] cannot guarantee a fast and low overshoot response in the start-up period [1]. One solution is using non-linear and intelligent controllers, such as fuzzy controllers.…”

This paper presents a method of designing optimal integer-and fractional-order proportional-integral-derivative (FOPID) controllers for a boost converter to gain a set of favorable characteristics at various operating points. A Pareto-based multi-objective optimization approach called strength Pareto evolutionary algorithm (SPEA) is used to obtain fast and low overshoot start-up and dynamic responses and switching stability. The optimization approach generates a set of optimal gains called Pareto set, which corresponds to a Pareto front. The Pareto front is a set of optimal results for objective functions. These results provide designers with a trade-off look-up table, in which they can easily choose any of the optimal gains based on design requirements. The SPEA also overcomes the difficulties of tuning the FOPID controller, which is an extension to the classic integer-order PID controllers and potentially promises better results. The proposed optimized FOPID controller provides an excellent start-up response and the desired dynamic response. This paper presents a detailed comparison of the optimum integer-and the fractional-order PID controllers. Extensive simulation and experimental results prove the superiority of the proposed design methodology to achieve a wide set of desired technical goals.

“…Multivariable Multiple Input-Multiple Output (MIMO) robust control in these type of system has already been studied in literature, as in Gadoura et al (2002) and Rafiei et al (2003), where robust H ∞ is proposed. However, application to the real model and order reduction is not addressed.…”

in 4th IFAC Symposium on system, structure and controlInternational audienceIn this paper a complete robust control synthesis is performed for a hybrid power generation structure composed by a Fuel Cell and a Supercapacitor. The control strategies are applied to the DC-DC boost power converters associated to each power source. Multivariable PI control with H∞ performance, H∞ full and reduced order controllers are designed and compared. The multivariable PI controller is designed through an optimization procedure based on solving some Linear Matrix Inequalities. A μ-analysis and frequency/time response performances results shows the advantages of the different proposed control strategies

“…Various aspects of robust control of a buck converter, both in current and voltage control modes, have been discussed and reported [3]. Several non-linear control techniques such as the fuzzy control, H ∞ control, micro synthesis (μ) control and the sliding mode control have also been used [4][5][6][7]. But the problem with these techniques is that they involve laborious task of determining the weighting functions and their implementation is not easy.…”
