Adaptive Semiactive Cable Vibration Control: A Frequency Domain Perspective

Table 1

Evaluation of cable damping performance.

Control scheme	Second-mode excitation			Third-mode excitation
	(1/4L); (mm)	(%)	(N)	(1/6L); (mm)	(%)	(N)
Without control	25.01	—	—	12.59	—	—
Passive MR control	14.50	42.0	797.37	7.07	43.9	776.18
T-LQG control	12.59	49.7	409.28	5.84	53.6	375.82
AF-LQG control	10.79	56.9	517.27	4.95	60.6	472.09

Note. denotes the percent reduction of the controlled RMS cable response over the uncontrolled case.
