Distributed Parallel Computing with Low Cost Microcontrollers for High Performance Electric Vehicles
Victor Azevedo, J. Dionísio Barros · 2015
In this paper, we implement a distributed parallel system, to control, with high performance, a power DC-DC buck converter in electric vehicles. A Permanent Magnet Direct Current (PMDC) motor is used, capable of running at 14,4 kW in a continuous mode. Low cost microcontroller (MCU) is used to monitor and control in real time proporcional-integrativederivative (PID) controller. The Serial Peripheral Interface (SPI) protocol is used for communication between MCUs. The distributed parallel computing allows that the controller becomes cost effective and scalable. Implementing distributed parallel computing increased performance in 5 times with two microcontrollers and 10 times with three when compared to 1 microcontroller.
