Design and Simulation of the Proportional Control Law for Aircraft Angular Displacement Autopilot

摘要:

现代飞机越来越复杂的飞行任务对飞机控制系统性能提出了更高要求,而飞机控制系统性能的好坏与飞机自动驾驶仪控制规律设计的优劣关系密切。为此,对某型飞机自动驾驶仪的比例式控制规律进行了分析和设计,仿真研究了控制规律中的速率反馈及位置反馈的作用和选取原则,进而设计出性能良好的飞机角位移自动驾驶仪比例式控制规律。通过大量仿真比较与验证得到:所设计的比例式控制规律性能良好,飞机角位移控制系统具有较好的动态和稳态性能,控制系统的时域和频域指标均能满足性能指标要求。

Abstract:

In modern aircraft flight, more and more complex aircraft mission performance requirements had become more sophisticated, angular displacement autopilot control law design to ensure the merits of the aircraft flying normally plays an important role. For this reason, a certain type of aircraft autopilot control law of the proportion of type design, simulation analysis of the rate feedback and the principle of selecting and then a good performance of the proportional autopilot control law. Comparison by a large number of simulation and verification were that the designed autopilot proportional control law in good control system had good dynamic and static performance and the system’s time domain and frequency domain indices could meet the system requirements.
