Abstract

This paper presents the Perturbation and Observation (P&O) algorithm as Maximum Power Point Tracking (MPPT) method for the transient and steady-state analysis of DC series motor fed from Photovoltaic (PV) generator at different solar irradiance levels and various motor loading conditions. At each solar intensity, the maximum power point of Voltage/Current (V/I) characteristic of the PV generator is achieved by perturbation and observation algorithm. The dynamical analysis of the system is carried out at different solar intensities. The dynamical analysis has been further investigated after step changes in solar intensity levels with fixed load coupled to the motor. The steady-state behavior of the DC series motor is addressed at various solar irradiance levels. All numerical simulations are executed using MATLAB software package by building the code.
