Experimental Verification of PTC of OEW-PMSM drives with one step delay compensation

Electric vehicles and aeronautical applications frequently employ permanent magnet synchronous motors (PMSM). In electrical drive and power electronics, finite-state model predictive control methods (FSMPC) have recently been introduced as an alternative to traditional methods. The most effective control of FSMPC employed in electric vehicle applications is predictive torque control (PTC). PTC has torque and flux as control variables which are two dissimilar quantities hence require a weighting factor (WF). The improper design of WF will deteriorate the performance of the machine. By optimizing a cost function, the best choice of inverter switching states reduces the mismatch between references and the predicted values of control variables. In this paper the experimental results for PTC with one step delay compensation based Open end winding PMSM (OEW-PMSM) using d-SPACE 1104 are presented. The PTC method with one-step delay compensation is tested with Urban dynamo meter drive cycle (UDDC) and Indian Driving cycle (IDC) driving cycles using OPAL RT 1250 controller with frequent accelerations and decelerations to verify its application in Electric Vehicles (EVs).
