The ergodic control of a multidimensional diffusion process described by a stochastic differential equation that has some unknown parameters appearing in the drift is investigated. The invariant measure of the diffusion process is shown to be a continuous function of the unknown parameters. For the optimal ergodic cost for the known system, an almost optimal adaptive control is constructed for the unknown system.This research was partially supported by NSF Grants ECS-87-18026, ECS-91-02714, and ECS-91-13029. 相似文献

A normal mode, stability analysis is applied to a spherically symmetric fluid system which contains a constant surface charge. The stability of the system is analyzed for the situation in which the electromagnetic mass is only a small fraction of the total mass and also for the situation in which the electromagnetic mass is the total gravitational mass. This latter situation corresponds to that of a Poincaré-Lorentz fluid electron. 相似文献
