This study studies the performance of an integral force feedback controller for increasing the damping of lightweight flexible structures. Both methods of maximum damping and $H_{\infty }$ optimization are used to tune the parameters of the control system. Two modifications of the integral force feedback are proposed to compensate the effects of a soft stiffness to increase the authority of the actuator. Higher damping values are obtained by adding feedback terms to the integral force feedback. Optimal tuning, required actuator force, and stability are also discussed based on an academic model of a single-degree-of-freedom cable structure.

改进的积分力反馈控制器，用于轻质柔性结构

这项研究研究了一个整体力反馈控制器的性能，以增加轻质柔性结构的阻尼。最大阻尼和最大阻尼两种方法$H_{\infty }$优化用于调整控制系统的参数。建议对积分力反馈进行两种修改，以补偿软刚度的影响，以增加执行器的功能。通过将反馈项添加到积分力反馈中，可以获得更高的阻尼值。还基于单自由度电缆结构的理论模型讨论了最佳调整，所需的执行器力和稳定性。
