Real-Time Implementation of the PMSM Multi-Motors Sensorless Control System

This paper presents the structure of a Permanent Magnet Synchronous Motor (PMSM) multi-motor sensorless automation control system based on the Field Oriented Control (FOC) type method. It presents the description of the component blocks of each Master/Slave subsystem, the optimal tuning of the Master and Slave controllers by using a Particle Swarm Optimization (PSO) algorithm and estimations of the PMSM rotor position and velocity by using a Model Reference Adaptive System (MRAS) observer. In Simulink development software are achieved the numerical simulations to prove the performance of optimized controllers in case of uneven distribution of the load torque between Master and Slave. It also presents the implementation of a Supervisory Control and Data Acquisition (SCADA) system which is characterized both by the implementation of PMSM Master/Slave control algorithms in dedicated controllers and the communication between Simulink and LabVIEW development software based on the Open Platform Communications (OPC) technology.
