| Summary: | Research aimed at developing an accurate algorithm has produced a large number of different approaches for algorithm evaluation and comparison. They fail to define a general methodology for algorithm evaluation due to lack of a comprehensive theoretical justification of the experimental methods. The bilinear form approach has enabled definition of a comprehensive methodology for the analysis and synthesis of the algorithms. This thesis defines a methodology for algorithm evaluation using bilinear form approach. In order to obtain the steps of the methodology, three algorithms were considered. First, they were represented in matrix form that enables unique representation and easy comparison. The theoretical analysis of algorithm sensitivity is performed using formulas derived from the bilinear form approach. The results of the theoretical analysis provide a priori prediction of algorithm performance. The experimental testing is performed in two parts: testing with synthesized signals and testing with signals that closely represent actual waveforms. Testing with synthesized signals should confirm algorithm performance discovered in the theoretical analysis. On the other hand, testing with waveforms that closely represent actual signals, will evaluate algorithm performance under the compound effect of several parameters under the real fault conditions. Results of this phase of testing are used for the comparison of the algorithms. Combining and joining the results of the theoretical analysis and the experimental testing, the overall algorithm evaluation is performed. Since this approach enables evaluation of algorithm performance, the methodology for algorithm evaluation is constructed by following the same steps used in the analysis and the experimental testing. The illustration of the methodology steps is provided using one of the algorithms. The designed methodology can be applied to a large class of the algorithms to perform their evaluation. |
