This project is a practical control engineering project involving a combination of theory, programming and experiment. The aim in to apply negative imaginary systems theory to design and implement a feedback controller for a small experimental flexible beam. The student will need to construct their own apparatus which could consist of a small flexible beam with piezoelectric actuators and sensors. These actuators and sensors could be salvaged from a pair of cheap earbuds. Some electronics such as an op-amps may be needed to amplify the signals. The controller could be implemented on a low cost microcontroller such as a rasberry pi. Once the apparatus is constructed, measurements will need to be made to come up with a model of the system. Then a controller can be designed using the negative imaginary theory and implemented on the hardware and its performance evaluated.
