Suboptimal control for linear large-scale systems with small time-delay
具有小时滞的线性大系统的次优控制

The suboptimal control for linear large_scale systems with small time-delay is studied. First, all the increments of state terms and interconnected terms among subsystems are considered as additional disturbances. Then by using the non_delay transformation approach and the successive approximation method of differential equations, we transform a higher order two_point boundary value problem with time_delay and time_advance terms into a group of decoupled lower order ones without time_delay and time_advance terms. Finally, the definite iterative values of optimal solutions are taken as a suboptimal control law for the large_scale system. For the linear large_scale systems with small time_delay, iterative times computing suboptimal control law can be greatly reduced. Therefore, this approach is specially suited for the suboptimal controller design for the linear large_scale systems with small time-delay.
