Abstract :
A maximum power tracking method for separately excited or permanent magnet DC motors fed from photovoltaic generators through buck power converters is given. Positive feedback of motor speed with a developed control law is employed. Averaged state space equations are used to study the transient performance. Experimental results obtained from an implemented system are given
