The performance of any realistic optimal control law in a missile application is dependent on the estimation of final time, or equivalently, on time-to-go. Typically, an estimate of the range between the target and missile and the rate of change of this range is obtained from radar or other ranging devices; the time-to-go estimate is then calculated.

A direct stochastic sensitivity analysis algorithm is developed for linear dynamical systems having incompletely known input statistics. The new algorithm extends previous results by applying covariance propagation concepts which utilize as a forcing function the sensitivity covariance matrix associated with the uncertainty in the elements of the system(More)
