本文考虑了实际基本约束下的极点配置和镇定问题,即所设计的控制器必须是因果的,因为只有在这种情况下,控制器才能实时实现。证明了在严格真过程的情况下,当极点配置或镇定问题的解集不为空时,它总是包含一个非空非因果控制器子集。此外,根据因果控制器的集合,我们有三种情况之一:(1)集合是空的,(2)集合实际上只有一个元素,(3)存在因果解的子集。对于这两个问题,本文以构造相应的因果控制器集的指令的形式给出了完整的解决方案。文中以延迟双积分器为例,说明了具体的实现方法。
The paper considers the pole assignment and the stabilisation problem under the practically essential constraint, that the designed controllers have to be causal, because only in that case they will be realisable in real time. It is shown that in case of a strictly proper process, when the set of solutions of the pole assignment or stabilisation problem is not empty, then it always contains a non-empty subset of non-causal controllers. Moreover, according to the set of causal controllers, we have one of the three situations: (1) the set is empty, (2) the set has actually one element and (3) there exists a subset of causal solutions. The paper provides complete solutions for both problems in the form of instructions for building the corresponding sets of causal controllers. Drawing on examples of a double integrator with delay, the procedures are illustrated.
