Modeling of Complex Ultrasonic Motors for Controller Design

Ultrasonic motors present unique modeling 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. Using a Reduced Order Model created by Model Order Reduction of a Finite Element Model has shown great benefits. This whitepaper discusses how Maple’s advanced calculation capabilities supported this process.
