Dynamic behaviour of DC motor-based photovoltaic pumping systems under searching MPPT algorithms

The behaviour of searching maximum power point tracking (MPPT) algorithms utilizing direct duty ratio perturbation control is shown to exhibit nonlinear phenomena, including slow scale bifurcations and chaos like behaviour, when applied to a dc photovoltaic (PV) system. The performance characteristics of a dc photovoltaic water pumping system, in which the searching MPPT algorithm is applied at the frequency of the PWM signal of the converter, are examined. The nonlinear behaviour of the system is analyzed and the effects of different parameters on system performance are discussed.
