| Outline of Final Research Achievements |
We have proposed an iterative solution method for nonlinear stochastic optimal control problems using stochastic analysis and statistical sampling. In this project, first, we have extended this method to a nonlinear filtering problem. Second, a modeling method for a nonlinear stochastic system has been investigated, which is based on the parameter identification with the nonlinear filtering method. Third, we have provided a unified framework for stochastic optimal control, state estimation and stochastic system modeling by the path integral analysis approach. Finally, we have performed experimental verification of the proposed method with small unmanned helicopters. Optimal flight trajectories for the helicopters taking probabilistic uncertainties into account have been obtained.
