Abstract :
In the paper by Prayati (IEEE Trans. Ind. Electron., vol. 51, no. 6, pp. 1194-1207, Dec. 2004), the authors claim that a design methodology for the development of distributed control applications with focus on task allocation in heterogeneous systems has been defined and that an algorithm was developed for the allocation of the application´s components to the system´s devices. They also present a case study to highlight the presented approach. In this letter, it is argued that the number of errors, obscurenesses, and inconsistencies that exist in the described approach, i.e., the methodology and algorithm, raises many questions about the effectiveness of the methodology and the correctness of the algorithm as well as their application in the presented example
