DesignDRIVE Fast Current Loop - An Introduction

00:22:28 | 24 AUG 2017
This video describes the need for higher control bandwidth in motion/servo control applications and why the current loop bandwidth is the most important. Next, the challenges and benefits of using immediate mode PWM updates is discussed followed by an illustration of how the architecture of C2000™ MCUs make sub-cycle updates possible.  The measured timing results and initial current loop bandwidth results are shown, as well as architecture comparison between a C2000 MCU and an FPGA-based drive.
