Vibration Isolation of a Surveillance System Equipped in a Drone with Mode Decoupling

Vibration isolation with mode decoupling plays a crucial role in the design of an intelligent robotic system. Specifically, coupled multi-degree-of-freedom (multi-DOF) model accurately predicts responses system dynamics; hence, it is useful for vibration and control decoupling. This study presents method based on identification, including multi-DOF to systems. Moreover, entire procedure described, derivation governing equation model, estimation frequency response function, parameter using least squares approximation. Furthermore, suggested methods were applied mobile surveillance suffering from resonances coupling; made monitoring performance camera deteriorate. The resonance problem was mitigated by installing isolators, but limited eliminate coupling effects natural deterioration performances isolation. More seriously, identification simple decoupled limits prediction this phenomenon. Hence, difficult enhance isolators. In contrast, presented can predict phenomenon critical Therefore, dynamic characteristics predicted isolator three-DOF final suggestion here. experiments demonstrated that configuration decreased up 98.3%, 94.0%, 94.5% operational range, i.e., 30–85 Hz, compared original fore-after, side-by-side, vertical directions, respectively. analysis suggests present effectively optimize drone containing
