This paper proposes a suboptimal guaranteed cost fuzzy control design for a class of nonlinear coupled systems, which are described by an n-dimensional nonlinear ordinary differential equations (ODEs) and a semi-linear scalar parabolic partial differential equation (PDE) connected in feedback. Initially, the nonlinear coupled system is represented by a Takagi-Sugeno (T-S) fuzzy coupled ODE-PDE model...
In this paper, an approximate constrained optimal guidance law is proposed for Mars entry vehicles guidance. Firstly, the original guidance of Mars entry vehicle is transformed into a fixed-time optimal tracking control problem, which depends on the solution of the Hamilton-Jacobi-Bellman (HJB) equation. Considering the case the control input is constrained, a generalized non-quadratic performance...
