Abstract:

This paper presents a full analysis and development of a system for vibrations reduction in a kitchen hood by using piezoelectric actuators. The control system is based on a feedback controller whose action depends on a single acceleration sensor collocated with the actuator. Two different resonant control laws have been designed: the first one operates without the information of the hood motor velocity; the second one is a more sophisticated controller which exploits also the velocity information. Overall, with the information of the motor velocity the best performances are guaranteed with a reduction of 75% of the vibrations. The resonant control system without the motor velocity information provides the best compromise in terms of performances (65% of reduction) and complexity of the implemented system. Tests held in anechoic chamber have shown the influence of the reduction of vibration upon the acoustic noise.

I. INTRODUCTION

AMONG the many different types of actuators for active vibrations suppression in flexible structures, piezoelectric transducers are considered the best compromise between achievable performances, costs and reliability (see e.g. [3], [4], [5], [6], [12], [14]).
