This paper proposes a new discretization method for logistic differential equations, for which the popular forward difference model causes chaos and overshoot unless the discrete-time period is chosen to be sufficiently small. While the exact discrete-time model gives exact values at discrete-time instants, it is not really a logistic equation anymore and requires an up-date of a complex gain at each...
An exact discrete-time model of a matrix differential Riccati equation that has recently been proposed is applied to a finite-horizon optimal control problem. This discretization method can always be used for a usual backward-in-time computation of a time-varying feedback control gain, which can be stored then in a memory for later use. Unlike existing methods that involve errors, the proposed algorithm...
An equivalence class, called the T-equivalence class in this study, is introduced for discrete time models of a continuous time system such that any member of this class has the same input-output characteristics when the discrete time interval approaches zero. This concept provides a systematic way of viewing the various discrete time models including those already proposed in the literature.
