The Control Theory (129) section does a real disservice to the field by insinuating it is little more than the study of Kalman filters. While an important model, the core results of control theory are without a doubt stability criterions.
The Lyapunov stability criterion is even quite elegant, despite being powerful: A system is asymptotically stable if there exists a function V where for x/=0, V(x)>0 and [Sum]_i (dV/dx_i) (dx_i/dt) < 0.

- theoh 8y ago> While an important model, the core results of control theory are without a doubt stability criterions. I'm guessing you mean "while they (kalman filters) are an important model...". What you've written involves a dangling modifier clause, which makes no sense.
