dkpy 0.1.3

D-K iteration in Python

dkpy

dkpy is a D-K iteration library written in Python, aiming to build upon python-control.

The package is currently a work-in-progress, and no API stability guarantees will be made until version 1.0.0.

Example

import dkpy
import numpy as np

dk_iter = dkpy.DkIterFixedOrder(
    controller_synthesis=dkpy.HinfSynLmi(
        lmi_strictness=1e-7,
        solver_params=dict(
            solver="MOSEK",
            eps=1e-9,
        ),
    ),
    structured_singular_value=dkpy.SsvLmiBisection(
        bisection_atol=1e-5,
        bisection_rtol=1e-5,
        max_iterations=1000,
        lmi_strictness=1e-7,
        solver_params=dict(
            solver="MOSEK",
            eps=1e-9,
        ),
    ),
    transfer_function_fit=dkpy.TfFitSlicot(),
    n_iterations=3,
    fit_order=4,
)

omega = np.logspace(-3, 3, 61)
block_structure = np.array([[1, 1], [1, 1], [2, 2]])
K, N, mu, info = dk_iter.synthesize(P, n_y, n_u, omega, block_structure)
