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 the lumber industry engineering system, all of the observation vector is often not available to its controller; it is again constrained by the bit rate when transmitted in a multi-channel approach with hysteresis and distortion. In recent years, many scholars have been seeking solutions, but so far this problem has not been well solved, which has drawn some scholars’ great attention. In view of this fact, this paper proposes the concept of controllable set in a class of systems, discusses the problem of state feedback control of linear continuous-time systems with communication constraints, gives and proves the sufficient and necessary conditions for the controllable of such systems, That is, the system is reachable if the system satisfies the conditions of the controllable set.
