An investigation of forced oscillation for signal stabilisation of two-dimensional nonlinear system

The phenomena of synchronisation, desynchronisation and forced oscillation has been studied using describing function theory for a two input and two output nonlinear system containing saturation-type nonlinearities and subjected to high-frequency deterministic signal (dither) for the purpose of limi...

Description
Summary:The phenomena of synchronisation, desynchronisation and forced oscillation has been studied using describing function theory for a two input and two output nonlinear system containing saturation-type nonlinearities and subjected to high-frequency deterministic signal (dither) for the purpose of limit cycle quenching. The analytical results have been compared with the results of digital simulation/MATLAB-SIMULINK for a typical example varying the nonlinear element.
