Attitude Control of Spacecraft by State Dependent Riccati Equation and Power Series Expansion of Riccati Methods [PDF]
فصلنامه علوم و فناوری فضایی, 2015 Attitude control of spacecraft in order to nonlinear and high order dynamics is fundamental and challenging issue. With respect to these nonlinearities, linear control theories are not suitable choices and spacecraft may be unstable or lose performance ...

State-dependent Riccati equation control with predicted trajectory [PDF]
Proceedings of the 2004 American Control Conference, 2004 A modified State-Dependent Riccati Equation method is used which takes into account future variations in the system model dynamics. The system in the state dependent coefficient form, together with the prediction of the future trajectory, may be considered to be approximated by known time-varying system.

State-dependent Riccati equation feedback stabilization for nonlinear PDEs
Advances in Computational Mathematics, 2023 AbstractThe synthesis of suboptimal feedback laws for controlling nonlinear dynamics arising from semi-discretized PDEs is studied. An approach based on the State-dependent Riccati Equation (SDRE) is presented for 2 and ∞ control problems. Depending on the nonlinearity and the dimension of the resulting problem, offline, online, and hybrid offline ...

Optimized discrete-time state dependent riccati equation regulator [PDF]
Proceedings of the 2005, American Control Conference, 2005., 2005 The state dependent Riccati equation was originally developed for the continuous time systems. In the paper the optimality of a discrete time version of the state dependent Riccati equation is considered. The derivation of the optimal control strategy is based on the Hamiltonian optimal solution for the nonlinear optimal control problem.
