Optimal controller/observer gains of discounted-cost LQG systems

The linear–quadratic-Gaussian (LQG) control paradigm is well-known in literature. The strategy of minimizing the cost function is available, both for the case where the state is known and where it is estimated through an observer. The situation is different when the cost function has an exponential discount factor, also known as a prescribed...

Linear quadratic regulator design for an unpowered, winged re-entry vehicle

Control synthesis for linear parametric time-varying systems

Designing auto-pilots with classical controller design methods such as root-locus may be a laborious job and it requires a lot of experience to arrive at satisfactory controllers. The single loop closure techniques that are common practice for most aircraft manufacturers are mainly appreciated because of the vast amount of experience gained in...
