ABSTRACT: This paper presents the perturbation and observation (P & O) algorithm as maximum power point tracking (MPPT) method for the dynamical analysis of DC shunt motor fed by photovoltaic generator at different solar irradiance levels. At each solar intensity, the maximum power point of current/voltage (I/V) characteristic of the PV generator is achieved by perturbation and observation algorithm. The nonlinear behavior of (I/V) characteristics of the PV generator at various solar intensities and the magnetization curve of the ferromagnetic material of the DC shunt motor are described by high order polynomial mathematical expression. The dynamical analysis of the DC shunt motor fed by PV generator at different solar intensity has been carried out, also the dynamical analysis of DC shunt motor is investigated at a step change in solar intensity levels with fixed load at motor.
