With the continuous development of intelligent manufacturing technology, the application of medium- and high-frequency power supply dust removal technology in the dust removal field is also increasing. However, medium- and high-frequency power supplies are affected by different voltage waveforms during dust removal control, so the waveform matching problem of medium- and high-frequency power supplies currently urgently needs to be solved. This study will integrate the Hausdorff distance algorithm with the hill climbing algorithm to extract the features of voltage waveforms and match them based on the features to find the matching waveform. The study first studies the matching of medium- and high-frequency voltage waveforms based on the improved Hausdorff distance algorithm. Then, based on improving the Hausdorff distance algorithm, a hill climbing algorithm is introduced to search for wave points in the waveform matching process. Finally, simulation experiments and practical applications are used to verify the performance of the waveform matching method in the dust removal control of medium- and high-frequency power supplies. The results showed that the average matching accuracy and matching efficiency of the research method were 89.71% and 78.92%, respectively. The stability, accuracy, recognition time, and recognition rate of the waveform matching method were 82.39%, 90.43%, 3.7 ms, and 95.16%, respectively. Through comparison, it was found that the performance of the research method is significantly better than that of the comparison method, indicating that this method can effectively improve the matching accuracy of power supply dust removal control and has good application prospects in the medium- to high-frequency field.
