Ultrasonic motors, used in cameras and other applications, present unique modelling challenges. The phenomena created in which ultrasonic waves with high frequencies are produced are difficult to capture in a model. The model must be accurate and execute quickly to be useful for controller design. Current modeling techniques have drawbacks. However, the use of a Reduced Order Model created by Model Order Reduction of a Finite Element Model has shown great benefits. With help from Maple’s advanced calculation capabilities:
the complex modeling challenges were alleviated
an accurate model of a USM was created
the model was created within a fraction of the time previously required with other modeling techniques
IEA report shows nuclear sector booming despite costs
Delays, in the UK, over approval of nuclear, seem to be the major issue (such as for SMRs). The report is about market finance and does not address...
