As a fist step the existing pendulum model will be studied in order to acquire some knowledge of the modelling requirements that are needed to compose a model in this field. Studying existing models helps revealing limitations and identifying possible areas for improvements and further scope. A model of a simple pendulum suspended on a string will then be constructed using EDEN. This model will take account of all the elements of a pendulum apparatus (blob, suspending string, etc) used in lab for carrying out experiments. This model will enable the user (engineer/designer) to interact with the pendulum by altering the physical properties of the materials such as the length of the sting, the mass of the blob, gravity and friction. The motion of the pendulum will be simulated visually using animation (by using Donald and Scout) and will allow the user to experience the effect that his interaction with the model has on the movement of the pendulum.
As an extension to the above, a feedback control system will be incorporated in the model. The extended model will include an inverted pendulum suspended on the top of a moving cart on a track. A controlled embedded within the cart will guide the cart back and forth, according to the current position of the pendulum, in such way that the blob will always remain balanced on the air and not fall down. The controller with be able to read the current position of the pendulum and accordingly alter the voltage on the motor of the cart in order to bring it in the desired position relative to the pendulum.
For successful implementation for both simple pendulum and feedback control models a deep level of understanding of the underlying physics and engineering principles is mandatory. Therefore a number of relevant references and literature will be consulted.
