MAN-MACHINE CONTROL INTERFACE - PURSUIT CONTROL

Man/machine control interface descriptions are complicated by the versatility of the human controller as an information processing device. System input interface characteristics can lead to control behavior ranging from open-loop (precognitive), through combination open-loop, closed-loop (pursuit), to closed-loop (compensatory) control structures. The pursuit scenario described here uses driving as an instance of preview, and finds that nearly ideal open-loop control combined with a compensatory (error-correcting) system is achieved. A new concept is presented for determining certain conditions under which pursuit behavior can be effectively achieved by the human operator in a manual control system. © 1979.
