چکیده
This brief addresses the problem of instability occurring in voltage control mode a non-minimum phase (NMP) DC-DC boost converter. To solve this issue presence uncertainties and external disturbances, quantitative feedback theory (QFT) is adapted to systematically design robust proportional integral derivative (PID) controller, which realized using only sensed output as feedback. The advantages proposed PID QFT are: (i) it eliminates burden tedious ad-hoc tuning gains conventional approaches, (ii) current measurement not required, (iii) disturbance dynamics (input load variations) are included stage itself, further enhances rejection performance voltage, (iv) allows direct for converter despite bandwidth limitations. Extensive simulations experiments carried out validate efficacy controller disturbances compared its superiority over controller.

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...
