A technique for the use of a digital computer for simultaneous generation of feedback control system transient response and sensitivity to parameter variations is developed. The sensitivity model for a basic linear control system is a cascaded replica of the original system with the sensitivity pickoff points corresponding to the error and feedback signals of the original system. This is convenient for computer analysis with DSL/360. For systems with nonlinear elements, the sensitivity model is implemented by making the instantaneous gain equal to the slope of the nonlinear function. Sensitivity analysis is utilized for improvement of system performance, determining parameter tolerances, and predicting changes in the response due to parameter variations.
