A Class of SDRE-RRT Based Kinodynamic Motion Planners [PDF]
2018 Annual American Control Conference (ACC), 2018 A variety of LQR-RRT kinodynamic motion planners are built on the idea of solving a two point boundary value problem in an LQR manner for affine systems. These planners can also be used for controllable nonlinear systems only if its linearized model at the equilibrium state is also controllable, and the cost function reflects only a time/control trade ...

IEEE Access, 2019 This paper proposes a simplified near optimal control (NOC) scheme to reject the disturbances of interior permanent magnet synchronous motor (IPMSM) drives by minimizing the complex calculations in the Taylor series method required for solving the state ...

An Approach to Evaluate the Region of Attraction of Satellites Controlled by SDRE
WSEAS Transactions on Systems, 2022 The control of a satellite can be designed with success by linear control theory if the satellite has slow angular motions. However, for fast maneuvers, the linearized models are not able to represent the effects of the nonlinear terms.

SDRE- Suboptimal Approach for Robust Control of Multiple Arms Carrying a Load in Cooperation [PDF]
AUT Journal of Modeling and Simulation, 2023 In this paper, a new application of State- Dependent Riccati Equation (SDRE) is proposed as a framework to design a robust controller for the system of multiple cooperative arms with parametric uncertainties.

A Nonlinear Optimal Guidance Law with Terminal Impact Angle Constraint [PDF]
International Journal of Computational Intelligence Systems, 2011 State-dependent Riccati equation (SDRE) techniques are rapidly emerging as general design methods for nonlinear controllers. A nonlinear optimal guidance law with impact angle constraint is derived for planar engagements to attack stationary targets. The
