Application Note: AN-114 - Closed Loop Valve Control

This application uses a Harsh Environment Controller and controls a proportional valve and includes active feedback of the valve coil current. The application uses a setpoint and drives the valve coil to a constant current (using Pulse Width Modulation). Using the coil current as a setpoint, the control is accurate regardless of temperature changes.
