PMSM Parameterization from Datasheet
Two test harnesses that add confidence that a PMSM is correctly parameterized from a datasheet. It also calculates motor efficiency at rated speed and torque.
PMSM Parameterization from Measurements
Identify PMSM motor parameters from experimental measurements.
PMSM Iron Losses
A test harness for a Permanent Magnet Synchronous Motor (PMSM) that validates that the iron losses are as expected. The open-circuit test validates the main flux path losses which are defined to be 500W due to hysteresis and 1500W due to eddy current losses. The short-circuit test validates the cross-tooth flux path losses which are defined to be 200W due to hysteresis and 600W due to eddy current losses.
Stepper Motor Pull-in Characteristics
Parameterize and tune a stepper motor using manufacturer datasheet information and a test harness. The model is parameterized using numerical data extracted from a datasheet. The simulation generates pull-in torque characteristics that you can compare to a manufacturer-provided pull-in curve. To tune the stepper motor model, the example uses a test harness that varies the drive type and load parameters.
Pre-Parameterized Stepper Motor Block Validation
Demonstrates and validates a set of predefined parameterizations that are supplied with the Simscape™ Electrical™ Stepper Motor block. These predefined parameterizations are determined from manufacturer datasheets.
Identify Supercapacitor Parameter
Identify the parameters of a supercapacitor. Instead of collecting voltage and current waveforms from a real supercapacitor, this example generates voltage and current waveforms by running a simulation of a supercapacitor using known parameter values. Then the example applies a parameter identification methodology [1] to the waveforms.
Model Ferrite Core Using Magnetic Core Block
Adjust the Jiles-Atherton parameters to obtain a good fit for the B-H curve of a magnetic core. The Magnetic Core block uses the Jiles-Atherton model to define the relationship between the magnetic flux density, B, and the total field strength, H. You can parametrize the block by specifying the Jiles-Atherton parameters directly. Alternatively, you can parameterize the block using saturated B-H curve data or by specifying magnetic characteristics. If you do not specify the Jiles-Atherton parameters directly, the block estimates the Jiles-Atherton parameters based on the assumption that you have a saturated iron core. This estimate is not always accurate for other types of core, such as ferrites with small values of coercivity and remanence. Always check that the B-H curve the block uses matches your input data.
Parameterize Magnetic Core Block Using B-H Curve Data
Parameterize a Magnetic Core block using B-H curve data. This block represents a magnetic core with magnetic hysteresis implementing a Jiles-Atherton model.
Battery Parameter Extraction from Data
Optimization of the Battery block's parameters to fit data defined over different temperatures. It uses the MATLAB® optimization function fminsearch. Other products available for performing this type of parameter fitting with Simscape™ Electrical™ models are the Optimization Toolbox™ and Simulink® Design Optimization™. These products provide predefined functions to manipulate and analyze blocks using GUIs or a command line approach.
Solar Panel Parameterization Validation
Model a solar panel by using data from a manufacturer datasheet. This example uses the datasheet data to generate current-voltage and power-voltage curves for the solar panel. The power-voltage curve helps you identifying the peak power for a given irradiance level and panel cell temperature. This peak power is then useful when designing an inverter.
Solar Cell Parameter Extraction from Data
Optimization of the Solar Cell block's parameters to fit data defined over a range of different temperatures. It uses the MATLAB® optimization function fminsearch. Other products available for performing this type of parameter fitting with Simscape™ Electrical™ models are the Optimization Toolbox™ and Simulink® Design Optimization™. These products provide predefined functions to manipulate and analyze blocks using GUIs or a command line approach.
