Abstract-The dual-loop control strategy in hybrid reference frame (HRF) for single-phase voltage source inverters (VSIs) in islanded operation mode is studied, which applies a capacitor voltage shaping loop in the synchronous reference frame (SRF) and a capacitor current shaping loop in the stationary reference frame (HRF-based v+i c control strategy). This strategy is able to achieve the purpose of active damping, fast dynamic response and zero reference tracking error. However, due to the inherent characteristics of SRF-based voltage loop and the digital control delay, the performance of the system is degraded and the control parameter design of HRF-based v+i c control strategy shows great difficulties. To overcome these shortcomings, in this paper, a systematic parameter design guideline for HRF-based v+i c control strategy is proposed to ensure the system stability and optimize the performance of the system under control delay condition. The mathematic model of the HRF-based v+i c control strategy is established with the consideration of control delay in this paper. Based on this model, a satisfactory region of the system stability indexes can be obtained by stability specifications of the system and the optimal control parameters can be calculated according to the stability indexes selected from the satisfactory region. By using this method, the system stability and robustness can be guaranteed. Finally, the experimental results are presented to validate the effectiveness of the presented optimal control parameter design methodologies.Index Terms-Control delay, single-phase inverter, hybrid reference frame, islanded mode, parameter design guideline.

This paper develops a hysteresis band‐based multivariable sliding mode control (SMC) for the double input buck buck–boost fused converter. The considered converter is operated at a controlled output voltage, while supplied from two different levels of input voltages from two different sources. The proposed control is to ensure the faster time of responses during the variation in the dual references, the output voltage, and low‐voltage source current, simultaneously. The controller is developed by considering these two controlled variables, which are directly dependent on each other. This multivariable SMC is shown to perform successfully to maintain the controlled variables at their desired values despite the variation in the input voltage sources and also during perturbation in the load impedance. The stability analysis for the closed‐loop system is established with the Lyapunov method, which confirms that both of the controlled variables reach the desired stable band at the steady state. The control is implemented in the simulation environment for different operating conditions. A laboratory prototype is developed to implement the multivariable SMC. The experimental results successfully validate their simulated counterparts.

The boost‐flyback converter is a type of DC‐DC power converter that allows for efficient step‐up voltage conversion. Despite its potential for achieving high voltage gains, there is a lack of comprehensive analysis and practical implementation of reliable control methods for this converter. To date, only a few control techniques have been thoroughly examined and, more importantly, validated on hardware for this specific converter. In this paper, a comprehensive evaluation of two control techniques is presented, namely, zero average surface (ZAS) and hysteresis band (HB) control, for the boost‐flyback converter. Insights into the performance of these techniques and their applicability in real‐world scenarios are provided by experimental investigation. Experimental results have shown that the ZAS controller, while promising in theory, requires the inclusion of a secondary feed‐forward control loop to achieve accurate regulation of the output and effective disturbance rejection. This finding has highlighted the sensitivity of the ZAS control to measurement noise and the importance of careful consideration when implementing it in hardware. By providing a detailed comparison and insights into the performance of these control techniques, this study contributes to the advancement of control strategies for the boost‐flyback converter and guides future research in this field.
