Optimization of a 3-conductor Modal Filter with a Circular Cross Section by Evolutionary Strategies with Limitations

The paper presents a novel approach to optimizing a modal filter with a circular cross section according to the criterion of minimizing the maximum value of the output voltage using the global optimization method. The specifics of simulation and optimization of strip protective structures and protective cables are indicated. A method for optimizing a modal filter with a circular cross section is presented on the example of a 3-conductor modal filter using the evolutionary strategies algorithm with limitations. The practicality and appropriateness of using this method for optimizing protective cables is shown. The testing results for the proposed method are obtained when optimizing a 3conductor modal filter with a circular cross section using evolutionary strategies with a different number of calculations. As a result, for the exciting pulse with an EMF of 5 V, the minimum value of the maximum output voltage was 0.61 V. Meanwhile, preliminary optimization by heuristic search made it possible to achieve only 0.83 V. The optimization results for the modal filter with a circular cross section by heuristic search are compared with those received by evolutionary strategies algorithm. Perspective directions for further development of this research topic are outlined.
