摘要: This article deals with the sensor-less control of a DC Motor via SEPIC Converter-Full Bridge combination powered through solar panels. We simultaneously regulate, both, output voltage SEPIC-converter to value larger than panel voltage, and shaft angular velocity, in any turning senses, so that it tracks pre-specified constant reference. The main result our proposed scheme is an efficient linear controller obtained Lyapunov. based on measurements converter currents voltages, motor armature current. law derived using exact stabilization error dynamics model, from which static passive feedback derived. All values references are parameterized terms equilibrium point multivariable system: desired at its Maximun Power Point (MPP), velocity. switched realization designed average continuous accomplished by means a, discrete-valued, Pulse Width Modulation (PWM). Experimental results presented demonstrating viability proposal.
