Towards sub-optimal stochastic control of partially observable stochastic systems [PDF]

open access: yes
A class of multidimensional stochastic control problems with noisy data and bounded controls encountered in aerospace design is examined. The emphasis is on suboptimal design, the optimality being taken in quadratic mean sense. To that effect the problem
