Manipulative approaches of Lyapunov function for stochastic systems with time-delay

To reduce conservatism, we adopted two approaches, pre-computing and/or free-weighting matrices, to manipulate the Lyapunov functional candidates, where we incorporate the more terms, and used them to analyse the robust control problem for uncertain stochastic systems with time-delay successfully. Then, we gave numerical examples to demonstrate the effectiveness of the two approaches.
