| Research Abstract |
We considered the optimal control problem for a dimensional varying large scale system which consists of several sub systems.
Main results are following.
1. For a dimensional varying deterministic system
(1) Optimal control law including one for a dimensional invariant system
(2) Control performance degradation caused to patternized information
(3) Quadratic performance using a fuzzy control in the place of optimal LQ control
2. For a dimensional varying stochastic system
(1) Optimal state estimation law including one for a dimensional invariant system
(2) Estimation performance degradation caused to patternized information
3. Optimal control law to the LQG problem which is combined the control problem with the estimation problem for a dimensional varying stochastic system
