Abstract
In order to eliminate the static error of the classic two loop autopilot, the PI compensator is introduced into the control system. To enhance the robustness of two loop autopilot with PI compensator, an angle of attack feedback is introduced into the system. Using the method of pole-place, the controller parameters of different two loop autopilot topologies are deduced. The analytical results show that a well designed two-loop autopilot with PI compensator can introduce a zero in numerator which counteracts the first-order inertial loop in denominator. However, the two-loop autopilot with PI compensator and angle of attack feedback introduces the phase-lead compensation in the feedback-loop. The zero cannot cancel the first-order inertial loop in denominator, and it is dominated by the first-order inertial loop. This kind of autopilot topology has better robustness than others.
