Abstract :
In this paper, the constrained estimators are derived for continuous-time linear stochastic systems whose states obey state equality or inequality constraints. The principal idea is the projection of the Kalman estimate onto the constraint subspace. The estimator is extended to the identification problem to estimate the unknown parameters in the system matrix which are subjected to some inequality constraints.
