We propose a reconstruction of the initial system of ordinary differential equations from a single observed variable. The suggested approach is applied to a certain class of systems which includes, in particular, the Rössler system and other chaotic systems. We develop relations and a method to pass from a model that involves the observable and its time derivatives to a real original system. To this end, we first find a set of candidates of the system in an analytic way. After that, by additionally studying the system, we make a choice for the sought system.
► We solve the problem of reconstructing an original system by using one observable.
► We use a standard system that involves the observable and its derivatives.
► Relations between the coefficients of the standard and original systems are obtained.
► A complete set of candidate systems is used to choose the sought original system.
► We obtain Rössler system analogs with the coefficients or the structure changed.
