| Outline of Final Research Achievements |
In this research, we aim at the realization of true decentralized control in which weak connection of controlled systems is not assumed. The main results are as follows. It was derived that necessary and sufficient conditions to guarantee the stability and the LQ optimality for decentralized PID control systems with any controller structure. It was provided that concrete design algorithms achieving the stability of the decentralized control systems. Although a condition with respect to relative degree was assumed in the above two cases, the condition was relaxed by using parallel feedforward compensators. A design method of decentralized control was proposed under general conditions.
