假设t时刻的目标值为x（t），在一段连续时间m内，存在n个目标值，这些目标值的集合称为整体目标值，组成强耦合高维非线性系统。

Assuming that the target value at time t is x(t), in a continuous period of m, there exist n target values. The collection of these target values is referred to as the overall target value, which constitutes a strongly coupled high-dimensional nonlinear system.
