The constrained discrete-time state-dependent Riccati equation technique for uncertain nonlinear systems
… time state-dependent Riccati equation (SDRE) technique is extended to discrete-time under input and state constraints, yielding constrained (C) discrete-time (D) SDRE, referred to as CD-SDRE. For the latter, stability analysis and calculation of a region of attraction are carried out. …

INVESTIGATIVE STUDY OF CONTROL DESIGN FOR A CLASS OF NONLINEAR SYSTEMS USING MODIFIED STATE-DEPENDENT DIFFERENTIAL RICCATI EQUATION
State dependent Riccati equation (SDRE) plays an important role in nonlinear controller design. For autonomous nonlinear systems that can be expressed in linear form with state-dependent coefficients (SDC), SDRE-based controllers guarantee local asymptotic stability of the closed-loop system, under …

Analysis and Real-Time Implementation of State -Dependent Riccati Equation Controlled Systems
Finally, experimental real-time control using SDRE is addressed. The plant used is the Pendubot, a two-link underactuated robot, which is a highly nonlinear 4th order system. The SDRE control is calculated by solving the Algebraic Riccati Equation online and the Pendubot is regulated at one of its …

Near-optimal feedback guidance for an accurate lunar landing
… of the State-Dependent Riccati Equation (SDRE) technique for constrained nonlinear dynamical systems in finite time. In general, the solution procedure yields a closed-loop control law for a dynamical system with point terminal constraints. Being a closed-loop solution, this SDRE technique …

Experimental and simulation-based assessment of the human postural response to sagittal plane perturbations with localized muscle fatigue and aging
… with the state-dependent Riccati equation (SDRE). Parameters of the SDRE were optimized to fit the experimentally recorded kinematics. Unlike other forms of nonlinear control, the SDRE provides meaningful parameters for interpretation in the system identification. The SDRE approach was …

Advanced Modeling and Control Strategies for Charging Electric Vehicle Batteries
… it applies the state-dependent Riccati equation (SDRE) technique to develop a closed-loop optimal control strategy. For the purpose of optimization, the battery model aims to track a reference trajectory with a performance index which is minimizing the quadratic error between a reference and an …

Host-Pathogen Interactions of Secreted and Surface Staphylococcus Aureus Factors
Staphylococcus aureus is an opportunistic bacterial pathogen that can infect humans and other species. It utilizes an arsenal of virulence factors to cause disease, including secreted and cell wall anchored factors. Secreted toxins attack host cells, and pore-forming toxins destroy target cells by …
