[ What is claimed is:] [1.]1. A method of controlling a test system responsive to a drive signal to produce a selected response signal, the method comprising:(a) applying a drive signal to the system;(b) obtaining a response signal of the system to the drive signal;(c) generating a nonlinear system

[ What is claimed is:] [1.]1. A method of controlling a test system responsive to a drive signal to produce a selected response signal, the method comprising:(a) applying a drive signal to the system;(b) obtaining a response signal of the system to the drive signal;(c) generating a nonlinear system model using the drive signal and the response signal;(d) generating an inverse linear system model;(e) calculating a test drive signal using the selected response signal and the inverse linear system model;(f) applying the test drive signal to the nonlinear system model;(g) obtaining an actual response signal of the nonlinear system model to the test drive signal;(h) calculating an error as a function of the actual response signal and the selected response signal;if the error exceeds a selected threshold:(i) obtaining a new drive signal ; and(j) repeating steps (f) through (i) wherein the test drive signal is the new drive signal until the error is less than or equal to the selected threshold; and(k) applying the test drive signal resulting from steps (e) or (i) to a test system.
