摘要:For many stochastic hybrid systems in the real world, it is inappropriate

study if their solutions will converge to an equilibrium state (say, 0 or the trivial

solution) but more appropriate to discuss if the probability distributions of the

solutions will converge to a stationary distribution. The former is known as the

asymptotic stability of the trivial solution while the latter the stability in distribution.

In this talk we aims to determine whether or not a stochastic state feedback control

can make a given nonlinear hybrid differential equation, which is not stable in

distribution, to become stable in distribution. We will refer to this problem as

stabilisation in distribution by noise or stochastic stabilisation in distribution.

Although the stabilisation by noise in the sense of almost surely exponential stability

of the trivial solution has been well studied, there is little known on the stabilization in

distribution by noise.
