Abstract
The objective of this paper is to establish a new meaning of reliable control with passive redundancy from a viewpoint of cooperation between compensators by introducing a new idea of cooperation in respect of energy.
In this paper, “load” of a compensator is considered to be its output signal against an external command input (e. g., a reference signal). It is evaluated by its total energy (i. e., L2-norm). Then, a new idea: “reliable load-sharing” is introduced as a desirable situation where “loads” of all compensators are always reduced by operating together with other compensators.
It is shown that reliable control and reliable load-sharing can simultaneously be achieved by a configuration of compensators. As a result, a new meaning of reliable control can be established from a viewpoint of cooperation between compensators
