INVESTIGATION OF A SPLIT-PATH NONLINEAR FILTER

Abstract

Use of a split-path nonlinear (SPAN) filter for compensating control systems is investigated by analog computer and the results are compared with those obtained with linear compensating filters. Comparisons are made of the responses of four systems to step, ramp, and sinusoidal inputs using the ITAE (integral of time multiplied by the absolute value of error) as the criterion for judging performance. Compensated system sensitivity to gain variations is also investigated. Use of the SPAN filter as a compensator showed little or no over-all improvement compared with that obtained with a less complex linear filter.
