Automatic MTPA Tracking Using Online Simplex Algorithm for IPMSM Drives in Vehicle Applications

The Development and Application of MTPA Calibration Method Based on INCA FLOW and MATLAB

“…The real-time implementation of optimal MTPA current trajectory tracking can be classified into two groups: online MTPA control methods and offline look-up table (LUT) method. Online MTPA control methods include signal Article injection-based methods [14,15], search algorithms [16,17], online parameter estimation methods [18], etc. Nguyen et al considered that the desired torque can be correctly calculated and improves the energy consumption of the IPMSM, if the method combining MTPA and RLS takes effect [19].…”

A Torque Error Compensation Algorithm for Surface Mounted Permanent Magnet Synchronous Machines with Respect to Magnet Temperature Variations

“…However, the back-emf method is affected by not only the dead time at low speed but also machine parameter variations. A perturbation searching method was presented and MTPA can then be achieved regardless of parameter variation [16][17][18][19], but the dynamic performance is degraded because the perturbation search takes time. High frequency signal injection methods are proposed in [19][20][21].…”

“…A perturbation searching method was presented and MTPA can then be achieved regardless of parameter variation [16][17][18][19], but the dynamic performance is degraded because the perturbation search takes time. High frequency signal injection methods are proposed in [19][20][21]. Though MTPA operation is achieved regardless of parameter variations applying high frequency signal injection methods, not only the injected current signal results in additional loss in an inverter and a motor but also it results in undesired influence on the motor operation.…”
