Abstract
In a photovoltaic solar-vehicle system, many factors may present disturbances and thus affect its operation. Among the disturbing parameters are the variable output voltage of the photovoltaic generator (GPV) and unbalanced irradiation throughout a day, as well as both the variable load (considered as a resistor in our case) and duty cycle. For a better quality output voltage, the optimization of the transfer power, and the protection of the photovoltaic solar vehicle system, the following is required: a constant and non-oscillating tension in the continuous bus and the extraction of the maximum power generated by the photovoltaic array under variable climatic conditions, as well as a specific model of boost converter. This paper discusses the optimization of the transfer power between the photovoltaic array and load in the first step, the study of an average model of the direct current/direct current (DC/DC) converter, and finally the design of a stable and robust tension controller. The results achieved confirm the rightness of the proposed control structure, which is simple, robust, and can secure the stability and good quality dynamics of the controlled system, as well as ensure invariance against disturbances. Also, the average model of the DC/DC converter used was found to be efficient.
Highlights
The significant growth of modern cities has led to the increased the use of transport, which has led to increased pollution and other serious environmental problems affecting the health of living beings.Another problem is the gases produced by the vehicles; this need to be minimized by the control of emissions and the implementation of proactive measures
The phase number of this this converter converter was chosen chosen based on four four criteria, criteria, illustrated number was based on including in the reduction of thephase volume of the of inductors, the reduction of the root mean square (RMS)
The high performance of this average model of the direct current/direct current (DC/DC) converter is due to the least squares method used
