gmt_dos-clients_fem

A client for the GMT FEM crate gmt-fem.

lib.rs:

This module is used to build the state space model of the telescope structure

A state space model is represented by the structure [DiscreteModalSolver] that is created using the builder DiscreteStateSpace. The transformation of the FEM continuous 2nd order differential equation into a discrete state space model is performed by the [Exponential] structure (for the details of the transformation see the exponential module ).

Example

The following example loads a FEM model and converts it into a state space model setting the sampling rate and the damping coefficients and truncating the eigen frequencies. A single input and a single output are selected.

use gmt_fem::FEM;
use gmt_dos_clients_fem::{DiscreteStateSpace, DiscreteModalSolver, Exponential,
              fem_io::{actors_inputs::OSSM1Lcl6F, actors_outputs::OSSM1Lcl}};

    let sampling_rate = 1e3; // Hz
    let fem = FEM::from_env()?;
    let mut fem_ss: DiscreteModalSolver<Exponential> = DiscreteStateSpace::from(fem)
        .sampling(sampling_rate)
        .proportional_damping(2. / 100.)
        .ins::<OSSM1Lcl6F>()
        .outs::<OSSM1Lcl>()
        .build()?;
