Abstract
Mechanical impedance determining apparatus for the control stick of an aircraft, an aircraft simulator, or non-aircraft apparatus such as a video game. Impedance determination is accomplished by a feedback path connected from output to input of the control stick with feedback transfer function coefficients determined by operator election in order to achieve positive, negative, or zero mechanical impedance at the control stick. Electrical network and computer realization of the feedback signal transfer function are contemplated using s plane pole descriptions of overall stick and feedback path characterizing transfer functions.
