A methodology for the control of harmonics due to large distorting loads. The ideal electricity supply has a voltage of prescribed frequencey and value with a sinusoidal waveshape. Modern electronic equipment such as digital commuication equipment and automatic manufacturing lines draw non-sinusoidal currents which distort the voltage waveform. Electricity suppliers are responsible for limiting voltage distoration to levels set by national standards. Techniques have been developed to allow them ....A methodology for the control of harmonics due to large distorting loads. The ideal electricity supply has a voltage of prescribed frequencey and value with a sinusoidal waveshape. Modern electronic equipment such as digital commuication equipment and automatic manufacturing lines draw non-sinusoidal currents which distort the voltage waveform. Electricity suppliers are responsible for limiting voltage distoration to levels set by national standards. Techniques have been developed to allow them to determine the maximum level of current distortion to which a particular customer is entitled. This project will developand verify a method for determining if a particular customer exceeds that entitlement.Read moreRead less
Design and Control of Sensorless, Brushless, Linear Permanent Magnet Motors for Fluid Pumping. Many machines require reciprocating motion and achieve it by mechanical conversion of rotary motion. In particular, pistons for liquid pumping and gas compression are usually driven by a crank on a rotary electric motor. Driving the piston directly by a linear motor eliminates the cost, weight, inefficiency and wear of the mechanical conversion. This project will design, construct and test high efficie ....Design and Control of Sensorless, Brushless, Linear Permanent Magnet Motors for Fluid Pumping.

The small size and simplicity of the integrated system outlined in this project will significantly improve the effectiveness of maritime surveillance for homeland security whilst enabling substantially lower operational costs. The proposal aims to develop control and sensing techniques, enabling small rotary wing unmanned air-vehicles (UAVs) weighing less than 100 kgs to operate from small-size vessels. This will be achieved by resolving the current lack of integration between ship motion and the unmanned vehicle guidance systems. The proposed research will make substantial contributions in areas of ship motion prediction and sensing and hover control of tethered and non-tethered small helicopters.
