The objective of this paper is to propose both feedforward and feedback controllers designed by the Linear Quadratic Gaussian and Loop Transfer Recovery (LQG/LTR) methodology. The adoption of a two-degree-of-freedom controller with feedforward and state-feedback controllers can improve the disadvantages of high gain for only feedback controllers designed by the LQG/LTR method. This paper also derives the algorithms which can take all the time-domain, frequency-domain, and robust design techniques into a unified method. An example of F-16 lateral autopilot design is given, which shows that the proposed method is more robust to measurement noise and more practical in applications, and has better steady-state responses in time domain.
