Fault Tolerant Control for Civil Structures Based on LMI Approach

Table 2

Suppressing effect comparisons among the bared structure, TMD structure, AMD structure without faults, and AMD H∞ structure with faults.

Systems	𝑞1; cm	𝑞2−𝑞1; cm	𝑞3−𝑞2; cm	𝑞a−𝑞3; cm	𝐹𝑎(𝑡); kN
Bare system	4.04	2.81	1.68	—	—
TMD system	2.69	2.22	1.57	25.08	—
AMD system without faults using 𝐆∞	1.88	1.08	0.86	78.38	15.46
AMD system with faults using 𝐆∞	1.90	1.37	2.30	108.7	209.1
AMD system with faults using FTC	2.06	1.35	0.71	83.36	16.00

𝐆_∞ represents H∞ state feedback control.
