چکیده
Due to the nonlinear and nonminimum phase characteristics of buck-boost converter, design its controller has always been a challenging problem. In this paper, multi-index feedback linearization control strategy is proposed converter. Firstly, by constructing an appropriate output function, original system mapped into combination linear subsystem subsystem. Then, according structural these two subsystems, optimal theory adopted for make it have good performance, while subsystem, coefficient function adjusted ensure stability. Finally, based on Hartman–Grobman theorem, internal mechanism adjustment basis method are revealed; that is, adjusting law, poles configured achieve purpose static dynamic performance system. The simulation results show feasibility superiority using law

متن کاملA New Topology of Embedded Z-H Buck-Boost Converter
In this paper, a new embedded Z-H (EZ-H) buck-boost converter is proposed. In this topology, two identical dc voltage sources are embedded in a LC network in a series connection with the inductors. The proposed converter eliminates the shoot-through (ST) switching state and there is no need for a front-end diode. Other advantages of the proposed topology are having capability of buck and boost ...
متن کاملFeedback Linearization Control of a Three-Phase Buck-Boost DC-AC Inverter
Abstract-This paper presents a nonlinear control algorithm for a single-stage three-phase buck-boost inverter. In contrast to the linear control law that is formulated according to small signal model that is linearized around an operating point, the exact linearization that is directly based on the large signal model allows for the formulation of the control law over a wide operating range. Mor...
متن کاملSliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency
In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...
