Augmented System Approach for Fractional Order SMC of a DC-DC Buck Converter ?

چکیده
A class of switching system is studied in this paper. A Fractional order controller for Sliding Mode Control (SMC) is proposed to control such systems. An augmented fractional order system is considered in order to design the controller. Therefore, more information about the system is available and the controller will have more degrees of freedom than the integer one. The results can either be better than or at least similar to the integer one, regarding to the application. Furthermore, an observer is designed in order to estimate the augmented states. To show the e¢ ciency of the controller a DC-DC buck converter is used as an application. The results are compared with integer order sliding mode control. The simulation results shows the e¢ ciency of the proposed method to control DC-DC buck converter.

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...

In this paper, a strategy based on the Sliding Mode Control(SMC) is used to achieve the Boolean input for DC-DC buck converter. Three di¤erent surfaces are proposed in order to design integer order and fractional order controller. Unlike conventional methods, sliding mode controllers designed through this methodology directly produce Boolean control actions, avoiding the usability of pulse-widt...
