ABSTRACT:
A method and apparatus for testing the operation of a complex stabilization circuit in a closed-loop system (12, 38) is comprised of a programmed analog (60-72) or digital (80-86) computing system for implementing the transfer function of a load (12), thereby providing a predictable load. The digital computing system employs a table stored in a microprocessor (84) in which precomputed values of the load transfer function are stored for values of input signal from the stabilization circuit (38) over the range of interest. This technique may be used not only for isolating faults in the stabilization circuit (38), but also for analyzing a fault in a faulty load by so varying parameters of the computing system as to simulate operation of the actual load with the fault.
