在对象输出的采样间隔为控制输入保持间隔的整数倍的多速率系统中，提出了一种新的广义预测控制设计。我们设计了一个只有一个自由度的系统，然后，对于积分作用，我们将其扩展到两个自由度。由于积分补偿仅在建模误差或扰动出现时才显示，因此当没有这些时，积分补偿不会导致暂态响应恶化。此外，即使存在建模误差或阶跃型扰动，对象输出也收敛到阶跃型参考输入，因为显示了积分补偿。所提出的设计是基于状态空间表示的，因此它可以很容易地扩展到多变量系统。
This study proposes a new design for generalized predictive control in a multirate system in which the sampling interval of the plant output is an integer multiple of the hold interval of the control input. We design a system with one degree of freedom, and then, for integral action we extend it to two degrees of freedom. Because the integral compensation is revealed only when a modeling error or a disturbance arises, the integral compensation does not cause the transient response to deteriorate when these are absent. Moreover, even if there is a modeling error or a step-type disturbance, the plant output converges to the step-type reference input, because the integral compensation is revealed. The proposed design is based on a state-space representation, and hence it can be easily extended to a multivariate system.
