WebModern spacecraft usually have larger and more flexible appendages whose vibration becomes more and more prominent, and it has a great influence on the precision of spacecraft attitude. Therefore, the cooperative control of attitude maneuvering and structural vibration of the system has become a significant issue in the spacecraft design process. … WebMar 29, 2016 · Hence, it should be clear that Huygens’ setup of coupled pendulum clocks is an exciting and challenging nonlinear dynamical system, whose dynamical behaviour is far from being completely understood.
