Abstract
A compact field programmable gate array (FPGA)-based digital motor controller (), a method, and a design structure are provided. The compact FPGA-based digital motor controller () includes a sensor interface () configured to receive sensor data from one or more sensors () and generate conditioned sensor data. The one or more sensors () provide position information for a DC brushless motor (). The compact FPGA-based digital motor controller () also includes a commutation control () configured to create switching commands to control commutation for the DC brushless motor (). The commutation control () generates commutation pulses from the conditioned sensor data of the sensor interface (). The compact FPGA-based digital motor controller () also includes a time inverter () configured to receive the commutation pulses. The time inverter () converts the commutation pulses into a rotational speed of the DC brushless motor () to provide a linear feedback control parameter.
