Abstract System identification algorithms for linear time‐invariant (LTI) systems have been developed recently, which provide induced norm bounds on the difference between the true system and the identified one. The error bounds then allow the use of robust control design techniques with guarantees on performance of the real system. This note concerns the adaptation of robust H ∞ identification techniques to linear periodic discrete‐time (LPDT) systems. The paper focuses on the algorithm proposed by Helmicki et al. 13 and is based on a frequency‐domain approach to LPDT systems.
