Virk, G. S.; Warwick, K. Mismatch effects on discrete-time poles. (English) Zbl 0666.93048 IMA J. Math. Control Inf. 2, 49-60 (1985). The presence of mismatch between controller and system is considered. A novel discrete-time approach is used to investigate the migration of closed-loop poles when this mismatch occurs. Two forms of state estimator are employed giving rise to several interesting features regarding stability and performance.
