主 题:ARMAX model closed-loop identification output error recursive algorithm
摘 要:The joint problem of the recursive estimation of an optimal predictor for the closed-loop system and the unbiased parameter estimation of an ARMAX plant model in closed-loop operation is considered, A special reparameterized optimal predictor for the closed-loop is: introduced. This allows a parameter estimation algorithm for the plant model to be derived which is globally asymptotically stable in a deterministic environment and gives asymptotically unbiased parameters estimates under richness conditions.
