If you're talking about the example of your controlled feedback problem, then it is linear. A linear operator, f is an operator for which f(a*x+b*y) = a*f(x) + b*f(y) a and b are scalars, x and y are signals
It's not a tough concept. It's likely different from the vernacular use of the word "linear", but it has profound implications for analysis.
Examples of linear operators are convolution, filtering, fourier transform, or matrix multiplication. Linear operators have a space of functions called eigenfunctions or eigenvectors which decompose the operator.

i don't know what 'linear' means in this context. let's say, then, that no, it's not linear.
