Abstract: A recurrence identification algorithm with co variance matrix reset is presented.This algorithm uses co variance matrix reset, so as to cope with parameter estimation of fast time varying systems. Digital simulation results show that this algorithm is satisfactory for identifying the parameters with missile control systems.

Key words: missile control co-variance, idcntifying, algorithm co-variance matrix
