Course Description
The
main objective of this course is to study analysis and synthesis
methods of
optimal controllers and estimators for stochastic dynamical systems.
Optimal
control is a time-domain method that computes the control input to a
dynamical
system which minimizes a cost function. The dual problem is optimal
estimation
which computes the estimated states of the system with stochastic
disturbances
by minimizing the errors between the true states and the estimated
states.
Combination of the two leads to optimal stochastic control.
Applications of
optimal stochastic control are to be found in science, economics, and
engineering. The course presents a review of mathematical background,
optimal
control and estimation, duality, and optimal stochastic control.

Class Project
The
projects could be an extension of existing algorithms in the literature
or,
preferably, involve the original research ideas related to your current
research. Project should be chosen in consultation with Prof. Hwang.
The
schedule is as follows:
- Project Proposal
(two page summary) due March 26 (Thursday)
- Project report
(10-12 pages) due the dead week of classes
- Project
presentation: 15-minute presentation in the last week (before the final
week)
- The
proposal and report should be written in 11-size font with a single
line space.
Evaluation
- Homework 30%
- Class Project 70%
