Abstract:

A computer-implemented method for performing stability analysis for a digital motor controller includes receiving a reference signal to be injected into a digital speed control loop and controlling, by a hardware description language (VHDL) component, the injection of the reference signal into the digital control loop through a field programmable gate array (FPGA) hardware interface. The method also includes providing the reference signal to the digital speed control loop to determine a performance of the digital motor controller and receiving a feedback signal, at the FPGA hardware interface, from the digital speed control loop based on the reference signal. The method includes comparing the reference signal to the feedback signal to evaluate the performance of the digital motor controller and exporting a result of the comparing by the FPGA hardware interface to indicate the performance of the digital motor controller.
