stabilizing state feedback delay systems convex optimization
2015/7/13
For linear systems with delays, we define a new class of Lyapunov-like functionals that may be used to prove stability. We also show how we may design a stabilizing (delayed) state feedback for delay ...
Efficient Convex Optimization for Engineering Design
