3.2.3.1 Lab One: Open-Loop Control With SFRA

The objective of this lab is to get familiar with the TIDM-1001 hardware and control the output voltage using direct PWM period adjustments without feedback. Because this system is running open loop, the ADC measured values are only used for instrumentation purposes in this lab. The PWM period is adjusted using the Expressions Window. Optionally, SFRA GUI can be used during run time to get frequency response of the plant.
