IMU Position Estimator

Compare multiple IMU sensors or the error sources for one IMU model.

Overview The IMU Position Estimator app allows you to compare the results obtained by using multiple inertial measurement unit (IMU) sensors from a predefined list containing ADI’s sensors, such as: ADIS16507 ADIS16545 1 1 Sensor not yet released; scheduled early 2022. Please reach out to your local sales representative for more information about our automotive solutions. In addition to ADI’s sensors, the app also contains competitors' sensors marked as Competitor A, Competitor B, and Competitor C. Using the app, you can simulate the results and get the position error trajectory graph by customizing the following variables: Trajectory Iterations Sampling Frequency Getting Started Access the vLab page and navigate to Apps. Select the IMU Position Estimator app. Click Open App. Once a new project is created, you can see the Configuration field to your left and the Navigation Path View on your right. Figure 1. New project Configure 1. Choose the IMU Sensor(s) You can choose one or more IMU sensors from a predefined list containing ADI’s sensors, together with competitors' sensors. ADI’s sensors available for comparison are: ADIS16507 – compact size and performance IMU for applications such as last-mile delivery and drones. ADIS16550 – auto performance, auto qualified IMU targeted towards L4 applications. Competitors' sensors are marked as: Competitor A – this sensor has a medium cost and a medium performance. Competitor B – this sensor has a high cost and a medium performance. Competitor C – this sensor has a low cost and a low performance. 2. Add the Trajectory Inputs Once you selected the IMU sensor(s), you can add the parameters for Trajectory Inputs. 2.1. Choose a Trajectory for the IMU from the dropdown menu: Straight road with constant velocity 30 m/s Turn at constant speed 24 m/s (to stay below 0.4g friction limit) Soft brake, starting velocity 30 m/s, brake at 0.3g, no pitch angle Braking while turning, starting velocity 30 m/s, brake at 0.3g, no bank angle Road roughness, velocity 5 m/s, potholes or speed breakers create shocks Note: You can select only one option. 2.2. The Iterations must be configured considering the following: Only numerical values are accepted. Decimal numbers are not valid. The number of iterations must be between 25 and 100. Iterations lower than 50 are not recommended because the sigma position error output will not show very accurate results. 2.3. Enter the Sampling Frequency to determine the error domination considering the following: Only numerical values are accepted. Decimal numbers are not valid. The unit of measurement is hertz (Hz). The sampling frequency must be between 25 and 1 000 Hz. Sampling frequency lower than 300 is not recommended because it leads to faster error accumulation. Figure 2. Trajectory Inputs Run the Simulation After inputting (and double-checking) the values in your configuration, click Run. Within a few seconds, the IMU Position Estimator app will analyze the parameters you offered, and it will simulate the results in the Trajectory Output tab. Analyze Results In the Trajectory Output tab, you will find the trajectory graph for each selected IMU sensor. The graph will display the time (X-axis) and the 1 sigma position error (Y-axis). Figure 3. Trajectory Outputs Additional Features To look at graphs in more detail, you can click on the fullscreen icon to show the graphs on the entire screen. If you want to remove all the entered values from all the fields, click the reset icon on the top right corner of the Configuration panel.

Magnetic Field Sensors

Select a magnetic sensor of choice, customize the settings and simulate the results.

vLab Designer provides solutions for creating larger systems using existing applications and reuse blocks created by vLab community. Drag and drop components on the canvas, adjust parameters, connect the blocks, and hit run. It's so easy!

Overview The Magnetic Field Sensors app allows you to model and simulate the function of Analog Devices' anisotropic magnetoresistive (AMR) technologies, such as: ADA4570 ADA4571 ADA4571-2 Using the app, you will be able to simulate the component's function and collect critical data regarding its performance in settings relevant to your desired application, according to several variable parameters: Sensor and magnet relative position Magnet dimensions Material Temperature Tolerances and geometry Getting Started Access the vLab page and navigate to Apps. Select the Magnetic Field Sensors app. Click Open App. Choose one product from the dropdown menu: ADA4570, ADA4571, or ADA4571-2. Once a new project is created, you can see the Product and Configuration fields to your left and the Diagram of the magnet and sensor on your right. Figure 1. New project Configure 1. Sensor Position The Magnetic Field Sensors app can simulate use of the tool with either an end-of-shaft position or one in a linear travel setup (e.g., the magnet moving parallel to the sensor). Different sensor positions will present different configuration options. 2. Configuration Parameters The configuration parameters vary according to the sensor position. 2.1. For end-of-shaft positioned sensors input: Magnet Dimension Temperature Magnet Material, along with the associated remanence in militesla (mT) and temperature coefficient in %/Kelvin format Tolerances – the maximum of alignment error and run out for X and Y, both in millimeters (mm) The following information should be taken into consideration in end-of-shaft configurations: Geometry/Travel distances are not a concern in this situation, so these parameters can be ignored. Specification of tolerances is important as it will provide information about how much offset or runout the system can withstand. If the magnet shape has a diametric or split axial shape, you will need to enter diameter data as opposed to length and width; height is analyzed for all magnet shapes. 2.2. For linear travel sensor input: Dimension, in millimeters (mm): height, length, width, and magnetic distance to sensor package edge Geometry, in millimeters (mm): initial Z and X travel distances as well as travel in the -X direction Temperature values for maximum and minimum, in Celsius (°C) or Fahrenheit (°F) Because ADA4570 and ADA4571 can operate in environments with a maximum temperature of 150°C, do not set the high-temperature value greater than 150. Figure 2. Configuration Run the Simulation After inputting (and double-checking) the values in your configuration, click Run. Within a few seconds, the Magnetic Field Sensors app will analyze the parameters you offered, and it will chart the results in the tabs above the main field of the app: Magnetic Field Output Voltage Error Analyze Results Each result tab will present you with the following data: Magnetic Field tab – displays the magnetic field seen at the senor, in the X and Y axes, as the magnet is rotated through a full mechanical revolution. The strength of the magnetic field is expressed in militesla (mT) and is shown high, low and room temperatures and angles from 0 to 360 degrees (°). Voltage tab – shows waveforms displaying the voltage of the output signals at high, low and room temperatures as the magnet is rotated. Error tab – displays the simulated accuracy of the sensor (magnet, sensor and ideal ADC) when amplitude and offset calibrations are completed. Note: If simulating the ADA4571-2, the results will include data for both channels. Figure 3. Results Additional Features To see the exact magnetic field strength, voltage output, or system error as the magnet is rotated, hover over the desired spot on the chart with your mouse, and the data will appear in a small rectangular box. You can customize the results shown on the graphs. If you wish to remove or re-add a result, click on the corresponding temperature button above the chart (Low Temperature, Room Temperature, High Temperature). If you run different configurations, you can access and compare the results in the Run Results field by clicking Run 1, Run 2 and so on. To look at graphs in more detail, you can toggle the Run Results field on or off, or click on the fullscreen icon to show the graphs on the entire screen. You can download the data in each tab in various formats: to export the simulated values as CSV, click the CSV icon above the chart. to export a screenshot as PNG, click the picture icon above the chart.
