Notes:
The general problem of characterizing a nonlinear, physical process from its input-output records is examined. A method of identifying the class of nonlinear, time-invariant processes with switched two-level inputs and finite memories is successfully applied to several nonlinear systems. The identification model consists of a finite, orthogonal series expansion for the output as a function of the past of the input. Of particular interest is the characterization and synthesis of a nonlinear, continuous stirred-tank reactor. This system, as well as others that are investigated, is simulated on a digital computer and identified after an initial observation period. No specific knowledge of the unknown process is presumed; however, only moderately fast input switching is permitted. After synthesizing the identification model, the process and model outputs are compared.
