Abstract

Highlights: A guide is proposed to design and verify a reliability of the MPPT algorithm. The verification is in accordance with the automotive development process standards. A modified Perturb and Observe MPPT method is appliedand its optimized C-code is tested. A low cost solution for the hardware implementation of the controller is proposed. A good performance in term of tracking factor and speed. A compliance during the verification steps MIL, SIL and PIL. Abstract: This paper presents the design and verification process of the Maximum Power Point Tracking Controller in accordance with the automotive development process standards, which could be used in Photovoltaic charging stations or in on-board chargers of electric vehicles. Considered as an automotive embedded software, the designed MPPT controller follows a sequence of three tests of the Model-based design MBD Approach to be verified and validated. The ultimate aim is to present a road map to design, test and validate an embedded software of the MPPT algorithm in vehicle based software. We design a modified Perturb and Observe P&O algorithm, then we generate optimized C code for a 32 bit ARM cortex microcontroller. Next, the algorithm is simulated through Model-in-the loop MIL, Software-in-the loop SIL, and finally co-simulated through Processor-in-the-loop PIL technique in the low cost STM32F429 discovery development board. During all the different tests, the designed embedded software shows a high accordance with MPPT requirement and high performances.
