摘要:
The effects of sampled-data control on continuous-time linear stochastic systems are considered. For such systems the state covariance will vary during the sampling periods. Algorithms to compute this time-varying matrix are given. Due to this time variation, an averaged value of the covariance mairix is also introduced. Plants including an arbitrary time delay are accepted. Reasons for the intersample variance alterations are finally illustrated by two examples.
