Abstract:
In this paper we show that the dynamic performance of MEMS devices can be significantly enhanced using reduced-order modeling techniques and open-loop control via input shaping. Specifically, we apply this methodology to a variety of thermally and electrostatically actuated microstructures, extending our recent results presented in [1]. Input shaping is a popular open-loop control method used primarily for vibration reduction in high precision and high speed positioning equipment [2]. This approach is particularly well suited in applications where positioning feedback signals are not available, and therefore it is very relevant for MEMS.
