BO-HBM-ex

Description

The Python's tool BO-HBM-ex shows an example of the application of Bayesian Optimization [1] on a Duffing problem [2]. The Duffing's oscillator problem is here solved using Harmonic Balance Method and a continuation technique.

Duffing oscillator scheme.

The optimization problem can be written:

Find $(k_{nl}^*,\xi^*)$ such as

$$(k_{nl}^*,\xi^*)=\underset{(k_{nl},\xi)\in\mathcal{D}}{\arg\min}\,\underset{\omega\in[\omega_l,\omega_u]}{\max} \ddot{q}_{\mathrm{RMS}}(k_{nl} , \xi, \omega)$$

Installation

Get the source code from this repository. The example can be run after installation of dependencies with

pip install -r requirements.txt

Usage

The Python's scripts can be run only with Python 3.

Run solver of Duffing oscillator

The file respDuffing.py provides frequencies responses for displacement and acceleration on PDF pictures for $\xi=\{0.15, 0.3, 0.5, 1.\}$ ($[\mathrm{kg}\cdot\mathrm{s}^{-1}]$) and $k_{nl}=\{0.25,0.5,0.75,...,2\}$ ($[\mathrm{N}\cdot\mathrm{m}^{-3}]$) . Pictures are stored in ParamDuffing folder.

Following pictures show $\ddot{q}_ {\mathrm{RMS}}$ for a few values of $k_ {nl}$ for $\xi=0.15\,\mathrm{kg}\cdot\mathrm{s}^{-1}$ (a), $\xi=0.3\,\mathrm{kg}\cdot\mathrm{s}^{-1}$ (b), $\xi=0.5\,\mathrm{kg}\cdot\mathrm{s}^{-1}$ (c) and $\xi=1\,\mathrm{kg}\cdot\mathrm{s}^{-1}$ (d).

Run Bayesian Optimization on Duffing oscillator

The file OptiExp.py generates data of Bayesian Optimization's iterations. These data will be available on the directory ExpOptimDuffing which contains data for sample sets containing 10, 20 and 25 samples. Results are provided along BO iterations on CSV files and acquisition and objective functions are plotted in 2D and 3D.

The following pictures show the evolution of the acquisition and objective functions along BO's iterations applied on the Optimization of the Duffing Oscillator (minimization of the maximum of the acceleration along the frequency bandwidth $[0,2.5]$ ($\mathrm{rad}\cdot\mathrm{s}^{-1}$)). The initial sampling obtained with LHS contains 10 sample points.
