On the Dead-Zone in System Identification
1991 (English)In: Proceedings of the 9th IFAC Symposium on System Identification and System Parameter Estimation, 1991, 1410-1414 p.Conference paper (Refereed)
A prediction error method for parameter estimation in a dynamical system is studied.
The following problems are treated in this paper:
- When is the DZ estimate inconsistent, and what is the set of parameters which minimizes the criterion in the case of inconsistency?
- What happens to the variance of the estimate as the DZ is introduced?
- Does the deadzone give a better estimate than LS when there are unmodelled deterministic disturbances present?
- What are the relations between identification with a deadzone criterion and so called set membership identification?
