Practical Methods of Calculation Involved in the Experimental Study of an Autopilot and the Autopilot-Aircraft Combination
Abstract
Practical method are presented for making the various calculations required for the analysis of an autopilot and an autopilot-aircraft combination from frequency-response data. Equations are derived for determining the servo-system error voltage for both displacement input signal and displacement plus rate of displacement input signals, the autopilot frequency response for addition of rate of displacement input signal, the servo-system frequency response for a change of gain, and the relation between open-loop and closed-loop frequency responses for the servo-system and for the autopilot-aircraft combination. Where possible, comparisons are made between experimental data and calculated responses using the equations developed.
