摘要: An original approach to Predictive Torque Control “Split and Seek” (PTC SS) for Mono-Inverter Dual-Parallel Permanent Magnet Synchronous Machines (PMSM) system is presented. Only one cost function both PMSM defined be minimized through the PTC approach. Unlike Master-Slave classical control, solution of will depend on references. The principle this extend possibilities control by offering additional virtual vectors find vector which minimizes function. This process includes two steps: first searching angle second magnitude. A model used predict behavior in next sampling interval under these different voltage vectors. After that, space modulation (SVM) technique applied synthesize vector. Simulations were built Matlab/Simulink software verify applicability new obtained results synchronism machines correct current tracking load speed conditions. performance improvement highlighted from specific tests.
