Existence of SDRE stabilizing feedback
IEEE Transactions on Automatic Control, 2001The state-dependent Riccati equation (SDRE) approach to nonlinear system stabilization relies on representing a nonlinear system's dynamics in a manner to resemble linear dynamics, but with state-dependent coefficient matrices that can then be inserted into state-dependent Riccati equations to generate a feedback law.

Detection and Estimation of Fault on Planar Cable-Driven Parallel Robot: SDRE Approach
International Conference on Computer and Information Application, 2023Detecting actuator malfunctions is critical for the Cable-Driven Parallel Robots (CDPRs), as these faults can lead to total system failure. This paper presents a model-based fault detection method for planar CDPRs.

Manipulator path control using SDRE
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000A controller synthesis based on state dependent Riccati equation methods is presented. The methodology is applied to the path control of a slow moving robot manipulator, for the purpose of method validation. Due to hardware limitations, not all the manipulator joints were controlled, and the resulting gains are obtained off-line using numerical ...

Alternative SDRE Scheme for Planar Systems
IEEE Transactions on Circuits and Systems II: Express Briefs, 2019Considering the state-dependent Riccati equation (SDRE) scheme, this brief formulates an alternative viewpoint on the flexibility of state-dependent coefficients for nonlinear affine planar systems. By constructing the feasible SDRE controller values directly, pointwise solving the Riccati equation can be circumvented.

Attitude control using the SDRE technique
7th International Conference on Control, Automation, Robotics and Vision, 2002. ICARCV 2002., 2004Attitude control is always considered as a nonlinear control problem. The state-dependent Riccati equation (SDRE) method of nonlinear suboptimal regulation is applied here to the attitude control of a rigid spacecraft. The saturated control is also considered by gain scheduling when using the SDRE method.

Application of SDRE control to servopneumatic drives
2010 IEEE International Conference on Control Applications, 2010Servopneumatic drives are characterized by significant nonlinearities due to the compressibility of the air, nonlinear characteristics of the servo valve and high static friction forces by the sealing utilities. To achieve high accuracies in positioning control these nonlinearities have to be considered in the control design.

SDRE-Based Suboptimal Controller for Manipulator Control
2019 12th International Workshop on Robot Motion and Control (RoMoCo), 2019The paper presents modelling and control of a robotic arm. To solve the control problem, the state-dependent Riccati equation (SDRE) method is applied. As a new contribution, the paper deals with state-dependent parametrization as an effective modelling of robot manipulator and shows how to modify classical form of the SDRE method to reduce ...
