Consensus Vibration Control for Large Flexible Structures of Spacecraft With Modified Positive Position Feedback Control

Trajectory Tracking and Vibration Control of Flexible Beams in Multi-Axis System

“…The Eq. (20) shows that the flexible beam vibration is equivalent to adding two poles to the system. And the disturbances Td include friction and load torque, and the transfer function can be described as [37] ( ) ( ) 1 ( )…”

“…Positive position feedback (PPF), proposed by Caughey et al [19], is an alternative control design technique for flexible structures with collocated sensors and actuators. In [20], the consensus modified positive position is adopted to suppress the vibration of large flexible structure with the large numbers of actuators/sensors in the spacecraft. PPF combined with variable structure control [21], extended multi-variable [22], H2 and H∞ optimization methods [23] are effective for active vibration suppression of flexible beams.…”

Group Consensus of Heterogeneous Multiagent Systems with Time Delay

“…Consensus problem of multiagent systems (MAS) has always been a hot topic in the control field. In recent years, due to the huge leap in electronic technology, the application of MAS is extremely extensive, mainly involving mechanical engineering, unmanned aerial vehicles, robot formations, neural networks and so on [1][2][3][4]. In previous studies, each agent had the same dynamic system, and their own attributes and traits were the same.…”

Stabilisation of a Flexible Spacecraft Subject to External Disturbance and Uncertainties

“…For the sake of control design, the models of flexible spacecraft are discretized in most of these works. Examples of these control schemes include fault tolerant control [1], optimal control [2], and positive position feedback control [3]. In [4], a variable structure control based on pulse-width pulse-frequency technology is designed to suppress the vibration of a flexible spacecraft with parameter uncertainties and input nonlinearity.…”
