在木材工业工程系统中,观测向量的全部对其控制器来说,经常不是可用的;而用伴随迟滞和失真的多信道方法传送时,又要受到比特率的约束.近年来,许多学者一直在寻求解决方案,但是到目前为止这个问题仍然没有得到很好的解决,这已经引起一些学者的高度关注.本文针对这一事实,提出了一类系统中的可控集的概念,讨论了具有通讯约束的线性连续时间系统状态反馈控制的问题,给出并证明了这类系统可控的充分必要条件,即如果系统满足可控集的条件,则该系统是可达的.%In wood industry engineering systems, the observation vector is often not available in its entirety to the controller, but a quantized version of it transmitted over a communication channel with accompanying transmission delays and distortion, subject to bit rate constraints. This problem has attracted some attention and progress is little in recent years. Feedback control problems for a linear continuous-time system with communication constraints are considered in this paper. The concept of set-controllability is introduced and testified for such a system. Moreover, sufficient and necessary conditions are provided for the systems' controllability, then the system can be reaching.
