Abstract The paper presents a novel application of the State Dependent Riccati Equation (SDRE) guidance approach with state constraints for chaser spacecraft in close proximity passive target. dynamics are described by full 6 degree freedom rigid-body relative motion. final trajectory is defined passively safe approaching cone, which acts as path constraint and follows attitude motion A Near Re...

In this research, an automatic control system is designed for landing of a small helicopter on a 4 DOF moving platform. The platform has three translational and one directional degree of freedom. The controller design approach is based on development of helicopter nonlinear dynamic model into the SDC (State Dependent Coefficient) form and real time solving of state dependent Riccati equation (S...

This paper presents the design of LQR (Linear Quadratic Regulator) and SDRE (State-Dependent Riccati Equation) controllers for flight control F-8 Crusader aircraft considering nonlinear model longitudinal movement aircraft. Numerical results analysis demonstrate that designed can lead to significant improvements in aircraft's performance, ensuring stability a large range attack angle situations...
