Analog filter realization for human — machine interaction in aerospace

摘要

Mathematical models of human behavior while flying an aircraft have been created for testing the physical and psychological state of pilots in aerospace. These models vary, but often they are characterized by a linear model with transport delay. Time constants in these models represent basic pilot skills, experience, and neuromuscular properties of a human. This article describes one of these mathematical models shown as a rational fraction function. The main purpose of this article is to analyze this model from the realization or implementation point of view. Two implementation methods are described here. The first is based on a state-space description using integrator synthesis. The second method is a physical circuit realization using active analog ARC filters. A model is created in the Simulink system to verify the state-space implementation. Parameters of this system are set automatically in the MATLAB environment. The analog realization part completes the previously published study of filter optimization. Together these articles make a complete research system of studies from pilot response tests to optimal model realization.
