Driving BLDC/PMSM with ePWM, eQEP, high-speed ADC, and FOC.
Motor control is realized with TI C2000 (TMS320F28xx). This article explains the roles of C28x, CLA, ePWM, eQEP, PWM synchronized ADC, and CMPSS, as well as the control loop for driving BLDC/PMSM using FOC (Field-Oriented Control) with CCS+C2000Ware. TechnoSphere, a company specializing in embedded contract development, provides an overview of real-time control microcontrollers.
