Abstract
The article proposes the analysis of the advanced PMSM model-based motor control strategies. These strategies are employed to optimize the system performance. The attainable performance was mathematically evaluated under the different methods with constant motor parameters. According to these equations, it is possible to observe how variables, such as current, voltage, apparent power, and power factor, vary with the developed torque under the different advanced control strategies. The model-based methods, specifically, the maximum torque per ampere and the unity power factor, were then selected to be simulated and implemented. The algorithms were experimentally verified on the traction PMSM with a low rotor saliency to clarify the steady state control performance. The model-based methods were tested under various load conditions with currents up to 100 A. However, slight deviations of the observed variables are present in the high currents region due to varying motor parameters.
