    ACME

    Accelerometer Models Extended: is a MATLAB/Simulink toolbox designed to model and simulate accelerometers. You can use it as a workbench for your accelerometer model alone, or integrate with XHPS for in-flight simulation. This toolbox is intended to simulate a variety of accelerometer types, with different geometries, sensor technology, actuation schemes, and so on. Hence, it is modular and parametric.

    Installation

    Download all files from the repository and add them to your Matlab path. All blocks are in the library (core/libAcme.slx), to use it, drag to your project and then use the appropriate setter function to initialize its parameters. The tutorials are in the simulations folder.

    Requirements

    Matlab 2021a

    XHPS 2022 (Optional)

    Features

    The blocks implemented so far will allow you to model a 1DoF GRACE-like ACC, with capacitive sensing and electrostatic actuation. Furthermore:

    • parameters accessible from script;
    • noise generation from ASD expression;
    • compatibility with XHPS for in-flight simulation;

    Please follow the tutorials to check its features. Let me know of any bugs, questions and suggestions.

    Proposed Features

    • noise source models;
    • a more complete dynamics system including
      • actuators with multiple electrodes;
      • rotational DOFs;
      • linearized DOF couplings;
    • novel optical sensors;
