The paper considers the reentry trajectory optimization of the hypersonic vehicle as an optimal control problem. The purpose is to design the optimal control law to ensure that the hypersonic vehicle maximizes the downrange under the heating rate, dynamic pressure and overload constraints. It is formulated as a constrained optimal control problem, where specific requirements of this reentry trajectory...
The design of robust tracking observer for a class of perturbed linear control systems is investigated in this paper. Based on the parametric solutions to a Sylvester matrix equation, the robust index and the matrices of tracking observer are parameterized and the problem of designing robust tracking observer is changed in to a minimization problem. A simple and effective algorithm for the design...
One of the biggest problems in designing or training RBF neural networks are the overfitting problem. The traditional design of RBF neural networks may be pursued in a variety of ways. In this paper, we present a method for the design of RBF networks to solve overfitting problem. For a practical application, frequency information is usually available for designing RBF networks by frequency domain...
The design of robust tracking observer for a class of perturbed descriptor control systems is investigated in this paper. Based on the parametric solutions to a generalized Sylvester matrix equation, the robust index and the matrices of tracking observer are parameterized and the problem of designing robust tracking observer is changed into a minimization problem. A simple and effective algorithm...
