On suboptimal selection of observation times in a linear discrete dynamical system

A suboptimal selection of observation times is considered which minimizes the quadratic control performance in the control and state error under a restricted number of observations. Two convenient observation algorithms are proposed for multiple available observations based upon the analytical results obtained for a continuous system, i.e. a periodic observation policy for an unstable system, and its modified versions, taking into account the transient state, for a -stable system.
