Double Pendulum RK4

QUESTION

Double Pendulum RK4

Asked 2021-Jul-12 at 00:04

I am trying to implement the classical RK4 algorithm to solve the system of differential equations which govern the equations of motion. However, I am having several problems for a while. The equations of motion can be written as below:

Since this is a system of first order differential equations, we are ready to use RK4 to solve it. However, I am really lost in regards to writing the system above in python code.

There is a related question here: System of second order ODEs Runge Kutta 4th order which writes the system of ODES for a different physical system into Python code and also uses RK4 to solve it. However, I have not been able to use that to make my own code work. There is another question I want to have the pendulum blob in my double pendulum which is closer to what I want, but it does not take care of the process by using arrays, but rather by writing several equations instead.

You are not using the passed state variable in the derivatives function, you just set the state to a constant. You should have a line like

Install double-pendulum

You can download it from GitHub.
You can use double-pendulum like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
