Active vibration control of a flexible beam using a non-collocated acceleration sensor and piezoelectric patch actuator

In this paper, the design of an acceleration sensor based active vibration control for a cantilever beam with bonded piezoelectric patches is studied. The problem of phase hysteresis and time delay caused by the non-collocated sensor/actuator pairs is considered. The system's dynamic model considering the non-collocated placement of the acceleration sensor and the piezoelectric patch actuator is derived. The phenomenon of phase hysteresis and...
