| Properties of a piezoceramic transducer at the interaction with a generator of limited power-supply are investigated. As a result of analysis of the largest Lyapunov exponent for the total system transducer-generator, the regions for three classes of steady state regimes - stationary, periodical and chaotic - are determined and the parameters for their realization are found. It is shown that chaos may originate only at accounting for the interaction between the subsystems. Under ideal electric supply, the processes in piezoceramic transducer do not have chaotic steady state regimes. |
