Algorithm 1 Fault isolation with structural residual analysis.
Input: R(s)
1:	k: the assumed number of simultaneously occurring faults
2:	is_ fault ← False
3:	if $r_i\left(t\right)$ > threshold then
4:	is_ fault ← true
5:	if is_ fault then
6:	for $k\le m$ do
7:	for $i\le C_k^m$ do
8:	Implement $C_k^m$$W^T$s
9:	$R_i^{*}\left(s\right)\leftarrow W_i^{T}R\left(s\right)$
10:	if $R_i^{*}\left(s\right)$ is isolated successfully then
11:	break
