Currently, many research studies reveal that for state regulator problems, the higher the degree of controllability is, the better the control effect likely is. Note that for the output regulator problems, the control performance is often evaluated by outputs. This article hence generalizes the concept and applications of degree of controllability to the case of output regulator. To this end, a kind of degree of output controllability is presented. Furthermore, simulations on wind turbines and the inverted pendulum system demonstrate that better control effect may be achieved by increasing the degree of output controllability measure. These results imply that similar to the case of degree of controllability for state regulation control, the degree of output controllability measure is likely a feasible candidate index for the design and optimization of the structural parameters of controlled plants in the case of output regulation control.

当前，许多研究表明，对于状态调节器问题，可控程度越高，可能的控制效果就越好。注意，对于输出调节器问题，控制性能通常由输出评估。因此，本文对输出调节器的情况概括了可控程度的概念和应用。为此，提出了一种输出可控性的程度。此外，对风力涡轮机和倒立摆系统的仿真表明，通过增加输出可控性度量的程度可以实现更好的控制效果。这些结果表明，与状态调节控制的可控制程度相似，
