Abstract
This paper presents a nonlinear fast terminal sliding mode control approach for a two-phase interleaved boost converter (2PIBC), emphasizing the utilization of inductor current estimation for achieving current sensorless control. The proposed approach introduces a state and disturbance estimation algorithm (SDEA) to effectively estimate the inductor current, external disturbances, system parameter uncertainties, and unmodeled dynamics within a 2PIBC. The combination of the proposed controller and SDEA enhances the robustness of 2PIBC, enabling it to track the desired reference voltage accurately. The stability of the proposed scheme is rigorously demonstrated through the application of Kharitono’s stability criteria. Furthermore, extensive simulations have been conducted to compare the response of the proposed controller with other state-of-the-art sensorless controllers. Finally, the hardware results are shown to validate and ensure the feasibility of the proposed work.
期刊介绍：
Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper.
The scope of Control Engineering Practice matches the activities of IFAC.
Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
