Hypersonic guidance via the state-dependent Riccati equation control method

Proceedings of the 1999 IEEE International Conference on Control Applications (Cat. No.99CH36328), 2003
In this paper, the state-dependent Riccati equation (SDRE) control method is used to design a guidance law for the midcourse phase of flight of a hypersonic vehicle. The guidance law converts flight path angle and heading angle commands to angle of attack and bank angle commands for input to an attitude autopilot.

Robust state dependent Riccati equation based robot manipulator control

Proceedings of the 2001 IEEE International Conference on Control Applications (CCA'01) (Cat. No.01CH37204), 2002
We present a new optimal control approach to robust control of robot manipulators in the framework of state dependent Riccati equation (SDRE) technique. To treat this highly nonlinear control system, we formulate it as a nonlinear optimal regulator problem.

Nonlinear closed loop optimal control: A modified state-dependent Riccati equation

ISA Transactions, 2013
The state-dependent Riccati equation (SDRE), as a controller, has been introduced and implemented since the 90s. In this article, the other aspects of this controller are declared which shows the capability of this technique. First, a general case which has control nonlinearities and time varying weighting matrix Q is solved with three approaches ...

The control system of hypersonic missile using state-dependent Riccati equation

SPIE Proceedings, 2006
This paper is to apply State Dependent Riccati Equation (SDRE) method, a recently proposed control method for nonlinear dynamical system, in the control system of hypersonic missile. Firstly a SDRE autopilot is designed and used in the control system, which concludes six blocks that are target, kinemics and proportional navigation guidance, BTT ...

Nonlinear model predictive control based on state dependent Riccati equation

2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA), 2014
In this work, we introduce an approach to nonlinear model predictive based on the so-called state dependent Riccati equation, SDRE. In this approach, the model is first cast in a form similar to the linear state space representation. Then the algebraic Riccati equation is constructed based on a similarity with the linear quadratic regulator to obtain ...

Real-Time Optimal Control of TRMS with State Dependent Riccati Equation

2018
In this paper, an optimal controller is designed for the twin rotor multi-input-multi-output (MIMO) system. The twin rotor MIMO system (TRMS) is a typical high order nonlinear system with significant coupling influences. The control outputs are positions in vertical plane and horizontal plane.

Nonlinear control of agile missiles using state dependent Riccati equations

Proceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997
The paper describes an H/sup /spl infin//-based approach using a state dependent Riccati equation (SDRE). It solves for a nonlinear H/sup /spl infin// control that satisfies the Hamilton-Jacobi-Isaacs partial differential equation. The nonlinear control law is formed around a gain scheduled linear solution, based upon the linearized dynamics, and adds ...

Re-entry Tracking Control Via State-Dependent Riccati Equations

2007
Sate-Dependent Riccati Equation (SDRE) method is applied here to track optimal entry trajectory which can be generated online by On Board Three Dimension Trajectory Generation. In this paper, the design of a longitudinal entry tracking control law based on SDRE was proposed in detail. Since its control value and weigh metric depend on the current state
