Abstract
This work presents a unified controller design scheme for step-up DC–DC converter topology having diverse dynamics. This scheme is based on indirect internal model control principle. Approximate frequency response matching method is utilized to get the proportional–integral–derivative controller from the equivalent internal model controller. The filter constant is selected by considering maximum sensitivity as the robustness parameter. The scheme is validated experimentally with (i) boost converter and (ii) high gain boost converter. The converters performance is tested under changes in reference command, input voltage, and load resistance. Further, robustness has been analyzed theoretically using small gain theorem and validated experimentally considering +40% change in inductor and capacitor values. A comparative analysis with recently reported work suggest improved servo as well as regulatory performance.
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.
