摘要：
The sampled-data H infinity optimal control problem is studied for time-varying systems. The problem consists of finding all sampled-data controllers with a piece-wise constant control signal for which the L2-induced norm from the continuous-time disturbance to the continuous-time output is less than a specified bound. A game theoretic approach is used to obtain a complete solution to the problem in the finite-horizon, time-varying case. The solution involves a mixed discrete/continuous Riccati equation, and a variable transformation which takes the problem to a standard discrete finite-dimensional H infinity filtering problem.
