Barrier Function-Based SDRE Control for Nonlinear Systems with State Constraints
Many real life systems operate in restricted state space. This study presents a new controller design technique for solving nonlinear regulator problems under the state dependent Riccati equation (SDRE) framework for systems with state constraints. A barrier function-based weighting matrix is designed to handle the state constraints. Stability analysis and constraint satisfaction are proved through Lyapunov analysis. The efficacy of the proposed method is demonstrated through a nonlinear benchmark problem and an application problem. The associated simulation results are also presented.
