摘要：
A new three-loop autopilot with singular perturbation margin is designed for the problem that the traditional three-loop autopilot can not insufficiently restrain the open-loop crossover frequency in engineering application. The proposed design method is used to introduce the singular perturbation margin information into three-loop autopilot. The densign and predictor-corrector of pole open-loop crossover frequency is made for three-loop autopilot, enabling the three-loop autopilot system to restrain the open-loop crossover frequency effectively without depending on the close-loop auto-oscillation frequency of control system. The calculated singular perturbation margin value can show the performance of control system. The experimental result shows that the three-loop autopilot system with singular perturbation margin can overcome the disadvantages of the traditional three-loop autopilot. The improved autopilot can restrain the interferential information effectively and quickly, and the work efficiency of control system can be shown from singular perturbation value. © 2018, Editorial Board of Acta Armamentarii.
