FOC PMSM Simulation Model Based on Current Hysteresis Control

In this article, we explore the FOC PMSM simulation model based on current hysteresis control. This model represents a commonly used technique that helps us better understand motor characteristics and behavior. We will discuss the advantages and disadvantages of this model approach, along with implementation methods for predicting motor performance. From a code implementation perspective, the current hysteresis controller typically compares the actual motor currents with reference values and generates switching signals to keep the current errors within a predefined hysteresis band. The simulation model likely includes Clarke/Park transformations for reference frame conversion, hysteresis comparators for current regulation, and space vector modulation components. We also present the testing methodology and validation results for this model, enabling readers to better understand its practical applications. The testing process probably involves parameter tuning of the hysteresis band width, evaluation of current tracking performance under different operating conditions, and analysis of torque ripple characteristics. Overall, this article aims to provide valuable information and insights for readers interested in motor control systems, particularly those working with field-oriented control implementations for permanent magnet synchronous motors.
