Real-time computational methods for SDRE nonlinear control of missiles

Computational speed and performance issues arising in the practical implementation of the state dependent Riccati equation (SDRE) technique are discussed. A software package for real-time implementation of the SDRE technique was developed during the present research. The execution of this software at speeds up to 2 kHz sample rates on problems of the size commonly encountered in missile flight control applications is then demonstrated on commercial off-the-shelf processors.
