Computer analog simulation of a model for the regulation of ago-antagonistic couples

A system of quadratic differential equations is proposed within the framework of 'non-linear mechanics', but also outside this framework in respect of certain features, and it is used with a view to formalising a feedback control system. The model helps to simulate states of balance or imbalance within an ago-antagonistic couple and to suggest methods for correcting the imbalances, which do not require modification of the parameter space. Its possibilities of synchronic or diachronic functioning are emphasised. The model may apparently be used for the construction of similar models which include several ago-antagonistic couples. Finally, the aims of such a model, which could be considered as an 'action' model, are defined; its place would be assigned midway between a black-box system and 'knowledge' models.
