基于前馈补偿的直升机控制律设计与仿真

摘要

以某型运输直升机为研究对象，根据飞行品质规范ADS－33 E的要求，在增稳控制的基础上，设计前馈补偿控制律，以改善系统的操纵性。通过拟合不同设计节点的前馈控制参数，实现包线内的调参控制律。对所设计的系统进行仿真试验验证，结果表明采用上述控制方案可取得良好的控制效果，证明了该方法的可行性和有效性。%Taking a transport helicopter as the research subject , based on stability augmentation con-trol , feed-forward compensation control law is designed to improve the control system according to the fly-ing qualities specification of ADS -33 E.By fitting the feed-forward control parameters of different flight nodes, parameter adjusting control law in the full scale flight envelop can be realized .The designed sys-tem is simulated and tested , and the results indicate that satisfied control effect is obtained by adopting the proposed control method , which proves the feasibility and effectiveness of the method .
