Study of the stability systems with a periodical behaviour of limit cycle type. I. Experimental studies

In this work the stability of the oscillating systems with a periodical behaviour of limit cycle type is studied under thermodynamic constraints or perturbations. For this purpose we studied the stability for the periodical trajectory of limit cycle type of the Briggs-Rauscher oscillating system using the following methods: by introducing perturbations in the systems according to a sinusoidal component and by introducing a foreign reactant in the Briggs-Rauscher system.
