SDRE missile guidance law

IEEE ICCA 2010, 2010
In this work, a state dependent Riccati equation (SDRE) missile guidance is formulated and studied. With the aid of a line of sight (LOS) fixed coordinate, the order of the system equations describing the three dimensional missile guidance problem is reduced to three.

A Newton Algorithm for Implementation of SDRE Controllers

AIAA Guidance, Navigation, and Control Conference and Exhibit, 2005
State-Dependent-Riccati-Equation (SDRE) is a recently introduced control method that attempts to establish a systematic procedure for dealing with a general class of nonlinear systems. Some of the known limitations of the SDRE techniques are the high computational load due to recurrent Riccati equation and the lack of an a priori global stability ...

Hiding in plain sight: immune evasion by the staphylococcal protein SdrE

Biochemical Journal, 2017
The human immune system is responsible for identification and destruction of invader cells, such as the bacterial pathogen Staphylococcus aureus. In response, S. aureus brings to the fight a large number of virulence factors, including several that allow it to evade the host immune response. The staphylococcal surface protein SdrE was recently reported
