Abstract :
The design of discrete-time linear-quadratic-Gaussian (LQG) controllers which yield closed-loop systems that match a provided model is discussed. The solution is in the form of a two-degrees-of-freedom controller, whose feedback and feedforward paths independently provide the optimal actions for disturbance rejection and model matching. Exact and approximate model matching cases are discussed in a unified fashion
