In this lecture, we will take a look at the fundamentals of distributed estimation and control. We begin by considering a random variable being observed by mutiple sensors. Under the assumptions of Gaussian noises and linear measurements, we will derive the weighted covariance combination of estimators. We will then touch upon the issues of distributed static sensor fusion and dynamic sensor fusion, i.e., distributing a Kalman filter so that multiple sensors can estimate a dynamic random variable. We then move onto the problem of distributed control and demonstrate, via a variant of the Witsenhausen counterexample, why distributed optimal control is nonconvex and nonlinear.
