Optimal digital feedback control systems counting computation time of control laws

Recently, the multivariable control theory studied up to date can be applied to many practical controlling problems. However, when the time constant of the plant is short and the dynamic order of the plant is high, the time delay arising from the computation time of control laws can not be neglected. In this paper, the author treats such a problem and proposes design methods of linear optimal regulators and optimal servosystems in which the delay arising from the computation time is counted properly.
