systems, and meets the needs of various clients as the designers and manufactures of hydrophones and sound_x000D_
projectors as well as consultants on the integration and testing of acoustic systems, primary to the oil and gas,_x000D_
defence and surveillance and environmental sectors. GeoSepctrum's products and services are wide ranging,_x000D_
including underwater acoustic systems, from transducer design to controls, software, winch and handling_x000D_
systems._x000D_
GeoSpectrum is developing a new, coherent, low frequency sound projector for seismic surveys (Coherent_x000D_
Seismic Source or CSS), and faces challenges in controlling the high amplitude signal generation and limiting_x000D_
harmonic distortion. Without better control of the sound source, the product will be inefficient and provide_x000D_
lower resolution imaging, while also having a more significant environmental impact. In order to deal with_x000D_
these challenges and improve its market position, the company needs to develop new control methods that are_x000D_
outside of their current capabilities._x000D_
Currently, the company is keen on working with Dr. Pan on the project that involves conducting research on_x000D_
the modelling, developing advanced control approaches for the acoustic system to generate a desired low_x000D_
frequency and high amplitude desired acoustic signal for underwater surveys. Potential methodologies to_x000D_
effectively reducing the harmonic distortion include iterative learning control, robust nonlinear control, and_x000D_
adaptive control with model identifications. Simulation studies as well as real time implementation will be_x000D_
investigated as well. The potential commercialization of the new device will place GeoSpectrum and Atlantic_x000D_
