Abstract :
Once a digital control system has been coded and implemented on a computer, simulation must usually be relied on for testing the controller. Proving that a controller is stable requires exhaustive testing. This note discusses the computation and application of frequency-dependent describing functions to nonlinear digital controllers once the controller has been implemented on a computer.
