Explicit Generalized Predictive Algorithms for Speed Control of PMSM Drives Fast Explicit Form with Field Weakening and Current Limitation

The paper deals with Generalized Predictive Control algorithms applied to the electric drives employing Permanent Magnet Synchronous Motors (PMSM). The Generalized Predictive Control (GPC) belongs to the multi-step model-based control design. The presented GPC algorithms are arranged in a specific explicit form for direct application in PMSM drives. The algorithms are supplemented with two front-end modules, which enable GPC algorithms to solve tasks of field weakening and current limitation. The design and implementation of proposed explicit GPC solution including modules are explained in the paper. The solution was experimentally verified at a speed control task. Performed experiments are documented by the time histories in oscillogram screenshots and figures.
