Optimal Rejection of Difference Bounded Disturbances
差分有界干扰的最优抑制

This paper formulates the problem of optimal disturbance rejection in SISO discrete-time systems where the disturbance is difference bounded. For controlled plants including or not including (1-z)-1, the solution of this problem is discussed respectively. It is proved that this problem is equivalent to general l1 optimal problem in these cases.
