Abstract : In previous work on differential approximation, it has been assumed that a black box under consideration may be described by a differential equation of a given type with unknown parameters, which are then determined by various optimization methods. In the present memorandum, this approach was extended to the case in which the black box comprises subsystems, each subject to its own differential equation, and in which switching occurs. Methods are explored of determining the nature of the subsystems, estimating the times at which switching occurs, and which subsystems are involved. (Author)
