This paper presents the methodology of tuning two position servo drive systems with Permanent Magnet Synchronous Motors (PMSM): Field Oriented Control (FOC) based on current model of motor and FOC based on voltage model of motor. These two strategies are Vector Control (VC) methods and provide a solution for high performance drives but the choice one of these algorithms determines the type of i...
