Application of Modern Control Theory to the Design of Man-Machine Systems.

摘要

The optimal control model of the human operator is reviewed. A new expression derived for the covariance matrix of the system states shows that a human-controlled plant is equivalent to an optimally controlled plant with added outside disturbance arising from the physiological limitations on man. Based on the characteristics of man,principles are proposed for the design of the two aspects on the man-machine interface,that is,the control dynamics and the display dynamics. Results from modern control theory are presented for the implementation of these principles. Model predicted performance improvement in the flight control of a light twin-engine aircraft simulator is compared with data from two experiments. The experimental data support the proposed design principles,in one case,even to a greater extent than the model predictions. (Author)
