of commercial aircraft. For any fixed wing aircraft actuators are needed to command the aerodynamic .... actuators introduced on the A380 transport aircraft ...

Summary:
Actuators are key elements of air-and spacecrafts.In the recent years the concept of the more-electric aircraft pushed the development of electrical actuation systems to substitute hitherto used hydraulic actuators in a broad range of applications such as flight control,landing gear and brake actuation.On top of that the superior dynamics of electrical actuators,especially when utilizing the piezoelectric principle,open new fields of application in noise and vibration control.

Novel electrical actuation technologies have to comply with demanding requirements concerning life,reliability,weight,environmental conditions and installation space. The main principles pushed forward in the recent years are electromechanical actuators (EMA)and piezoelectric actuators.These new actuators put strong requirements on electronics systems design and power amplifier stages.It requires highly efficient and reliable electronics to achieve flight worthy products.
