Modelling a Double Pendulum in Simulink

One module I took during the final year of my degree was ‘System Modelling and Simulation’. A well taught and great module, one of the tasks was to model a double pendulum.

The approach involved deriving the equations of from the highest order of motion for each mass then working backwards through Simulink blocks to generate each term, which could then be to solve the equation – a bit of a chicken and egg problem! It was a an excellent task as the idea seems a little backwards at first and gave me a fresh approach to problem solving a model.

Below is the method extract from my report as the YouTube demo has generated some interest in the solution.
