The fact that "receptors" occur in pairs is a general phenomenon in the world ofliving creatures. For mammals, the term "paired receptors" means that the two receptors,owing to the differences in structure or in spatial reation, respond to stimulus from thesame source in opposite ways. If one increases its discharge, the other decreases it.This paper considers the influence of such a pair of receptors in the performance of theliving system. First, series of biological facts have been listed to show that reference...

The fact that "receptors" occur in pairs is a general phenomenon in the world ofliving creatures. For mammals, the term "paired receptors" means that the two receptors,owing to the differences in structure or in spatial reation, respond to stimulus from thesame source in opposite ways. If one increases its discharge, the other decreases it.This paper considers the influence of such a pair of receptors in the performance of theliving system. First, series of biological facts have been listed to show that reference point of thehomeostasis and the posture maintenance in the living system may be determined by thepaired receptors. Secondly, on the basic assumption that the error-eliminating process satisfies thefollowing equation Id~2ε/dt~2+μdε/dt+kε=0,here ε-error, I, μ and k are constants, the authors suggest that the performance of theliving organism in the light of the principle of paired receptors would be improved. Somequantitative indexes have also been estimated. Finally, according to the principle of paired receptors the influence of the variationof element characteristics may be decreased.

生物界中感受器成对出现,乃是一种相当普遍的现象。所谓成对感受器是指这样的一对感受器,它们或者由于本身结构的不同,或者由于彼此之间空间关系上的不同,使它们在同一刺激源的作用下作相反方向的反应变化。如果其中之一的脉冲发放增加,则另一个的脉冲发放便减少。本文讨论了这种成对感受器对生物系统调节品质的影响问题。首先,列举了若干生物学事实,说明生物系统体内稳态和姿势维持中的给定值可能是由成对感受器特性曲线的交点所决定。其次,假设误差消除过程满足下列方程I(d~2ε)/(dt~2)+μ(dε)/(dt)+κε=0此处ε——误差,I、μ和κ是常数。在此基本假设下,作者证明运用成对感受器原理可以改善调节品质,同时估计了一些定量指标。最后,作者证明运用同一原理还可减少元件变性对给定值的影响。

In this paper, the (status of) several problems of hierarchical control are surveyed. The contents of this paper are as follows: In section Ⅰ, the auxiliary problem and relaxation principle which are based on infinite-dimensional programming are discussed in detail. By these two principles, a unified apprach is formed, which can be used to derive several basic decomposition-coodination algorithms. In section Ⅱ, the hierarchical method are used to obtain the closed-loop optimal control laws of linear and nonlinear systems; the on-line hierarchical control of the steady-state systems is also discussed. In section Ⅲ, the Stackelberg strategies applied to hierarchical control are surveyed. In section Ⅳ, two algorithms of state estimation for hierarchical systems are derived.
