In industry, a precise two-dimensional, high-precision motion control system is in high demand. Compared with other types of two-dimensional direct-drive machines available, the planar-switched reluctance motor has the advantages of low-cost, simple structure and it can operate in wide temperature ranges. Considering the machine structure of the planar-switched reluctance motor prototype, mechanical improvements are performed and a compact planar-switched reluctance motor has been constructed with more mechanical robustness. Since dynamic response errors for the planar-switched reluctance motor-based position control system under a typical proportional-differential controller increases with the frequency of position reference, a dual-loop position controller cascaded to the proportional-differential regulator is proposed. Both simulation analysis and experimental results verify the position controller';s effectiveness of reduced dynamic errors with increased frequency and precise tracking of reciprocating motion command.
