PID Regulator Implementation for Electric Kart DC Motor Current Stabilization

摘要

Motor drives are controlled using some sort of modern controller. In the past, operational amplifiers were used extensively as main computing elements. As digital technology has advanced, more sophisticated devices have become popular, like industrial programmable logic controllers (PLC) or microcontrollers (MCU) with necessary additional hardware. This article deals with MSP430 series microcontroller implementation in closed current loop regulator. Regulator task is to control permanent magnet DC motor of an electric kart.
