Correction to: Remarks on input-to-state stability of collocated systems with saturated feedback (vol 32, pg 293, 2020)

The following corrections should be made to this article. In Theorem 9 and Theorem 11, one needs to add the assumption that the admissible feedback function σ is globally Lipschitz continuous. If we denote the globally Lipschitz constant by k, then in the proofs of Theorems 9 and 11 the definition of r should be omitted and the constant kr replaced by k. Otherwise, the K∞-function candidate for the functions ρ in (7) would depend on the solution x and the disturbance d in both theorems.
