Performance Evaluation on an Active Hybrid Mount System for Naval Ships Using Piezostack Actuator

압전작동기를 이용한 함정용 능동 하이브리드 마운트 시스템의 진동제어 성능평가

In this work, a new active hybrid mount featuring piezostack actuator and rubber element is proposed, and its vibration control performance is evaluated by applying a robust frequency-shaped sliding mode controller. After describing the configuration of the proposed mount, vibration control performances are experimentally evaluated. A mount system with four active hybrid mounts is then constructed. To attenuate vibrations on the supported mass, a frequency-shaped sliding mode controller is designed and implemented to the system. Finally, control performances are obtained and presented in time and frequency domains via computer simulation.
