Abstract:
|
In recent years, Interior Permanent Magnet Synchronous
Machines (IPMSMs) have attracted a considerable
attention in the scientific community and industry for Electric
and Hybrid Electric Vehicle (HEV) propulsion systems. Lookup
Table (LUT) based Field Oriented Control (FOC) strategies
are widely used for IPMSM torque control. However, LUTs
strongly depend on machine parameters. Deviations of these
parameters due to machine ageing, temperature or manufacturing
inaccuracies can lead to control instabilities in the field
weakening region. In this paper, two novel hybrid IPMSM
control strategies combining the usage of LUTs and Voltage
Constraint Tracking (VCT) feedbacks are proposed in order to
overcome the aforementioned controllability issues. Simulation
results that demonstrate the validity of the proposed approaches
are presented. |
