Abstract

The problem of optimal measurement scheduling is considered for continuous-time linear systems with discrete measurements. More specifically, the problem of achieving a prescribed estimation accuracy at some given future time using a minimum amount of measurement resources is studied. The measurement scheduling problem posed requires the minimization of a linear function subject to nonlinear inequality constraints. This constrained minimization problem (i.e., nonlinear programming problem) can be solved numerically, and this is illustrated with simple examples. The application of optimal measurement scheduling to the problem of remote cueing of an interceptor missile for target acquisition is considered. For the remote cueing problem, the Doppler shift between the missile and target, a nonlinear function of the target and missile states, must be estimated and provided to the missile with a specified accuracy. A method for estimating the Doppler shift as well as a method for determining the accuracy of this estimate are presented. Numerical solutions for examples of measurement scheduling problems are also presented.
