PMSM_PM_Temp_Predict

PMSM_PM_Temp_Predict is a project aimed at predicting the temperature of the permanent magnet in a Permanent Magnet Synchronous Motor (PMSM). The temperature of the permanent magnet is an important parameter that affects the performance and reliability of the motor

Description

This project utilizes machine learning techniques to develop a predictive model for estimating the temperature of the permanent magnet in a PMSM. The model takes into account various input parameters such as motor operating conditions, electrical voltages and currents, and environmental factors to make accurate temperature predictions. More specifically: the Random Forest Regressor is used for this project.

Features

• API integration: The project provides an API that exposes the trained model, allowing other applications or systems to make temperature predictions programmatically
• Feature scaling: input data is normalized to meet regression model requirements
• Single sample processing: API contains the function to predict single temperature value based on current motor state
• Data frame processing: API allows you to process pandas DataFrame and get results for a huge amount of samples with one function call.

Getting Started

To get started with the PMSM_PM_Temp_Predict project, follow these simple steps:

1. Install package with pip install pmsm-pm-temp-predict This command will install this python package and all required dependencies.
2. Integrate the trained model into your application using the provided API
3. Start making temperature predictions using the API and your collected data

For detailed instructions and usage examples, please refer to the documentation included in the repository.

API

Two functions are provided by API of this package:

Single sample processing

temp_predict(u_q, u_d, i_d, i_q, coolant, stator_winding)

return value is a single float value which represents predicted temperature of the motor's permanent magnet.

Code example

import pmsm_pm_temp_predict as pms
print("Predicted permanent magnet temperature is: ", temp_predict(-0.450682,
                                                                   -0.350055,
                                                                   0.004419,
                                                                   0.000328,
                                                                   18.805172,
                                                                   19.086670))

Output: Predicted permanent magnet temperature is: 24.849657903061008

DataFrame processing

temp_predict_df(df)

return value is an array of predicted temperatures of the motor's permanent magnet.

Code example

import pmsm_pm_temp_predict as pms
print("Predicted permanent magnet temperature is: ", temp_predict(-0.450682,
                                                                   -0.350055,
                                                                   0.004419,

                                                                   18.805172,
                                                                   19.086670))

print("Predicted permanent magnet temperature is: ", temp_predict_df(pd.DataFrame({'coolant': [18.805172], 
                                                                                   'stator_winding': [19.086670],
