Multiple model control of a Buck dc/dc converter

Multiple model control of a Buck dc/dc converter

This paper describes a simple model estimator for a new control method based upon algorithms commutation between two linear control laws. The multiple model control (MMC) defined is based upon the fusion of only two traditional IP controllers outputs. The influence of the digital integration methods and of the noise are pointed out. This new strategy improves the performances of the step input ...

Designing a novel structure of explicit model predictive control with application in a buck converter system

This paper proposes a novel structure of model predictive control algorithm for piecewise affine systems as a particular class of hybrid systems. Due to the time consuming and computational complexity of online optimization problem in MPC algorithm, the explicit form of MPC which is called Explicit MPC (EMPC) is applied in order to control of buck converter. Since the EMPC solves the optimizati...

Sliding Mode Control for a Buck Converter

Chaotic behaviors of the buck converter were demonstrated by computer simulation studies. The paper implied theoretical considerations and simulations for this kind of converter using a sliding-mode control. The method tried to establish a periodic behavior from a chaotic one in converter behavior. Key-Words: buck converter, sliding-mode, control, bifurcation, periodic, chaotic

Sliding 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...
