## Abstract The suboptimal control policy obtained from series expansion of time‐delay terms is useful when the delays are small. The second method involving direct search on the constant gain matrix is applicable even for large delays. Both of these proposed methods are computationally simple and
AImtract--Industrial plants which contain unilateral flow of material are considered. First, it is shown that such plants can be represented by finite-dimensional difference equations after sampling. Then, the design of discrete-time optimal control systems is studied based on the difference equatio
Summing--The concept of singular sensitivity of a lumped linear system to small pure time delays in controls is introduced, From this, first order changes in a quadratic performance index can be calculated. A design method is proposed which calculates optimal linear feedback laws for the lumped syst
