Nonlinear Adaptive Control of Long-EZ Fixed-Wing Aircraft

在过去十年中，无人驾驶飞行器（uav）已广泛用于各种关键的军事和民用应用，例如监视，边境巡逻，搜索和救援，遥感和地理采样，森林火灾探测和战斗，电力/管道检查。为了使无人机更安全，更适合越来越多的潜在应用，无人机的可靠性和生存能力正成为人们最关心的问题。与载人飞行器相比，无人机的控制更具挑战性——所有的飞行控制、导航和制导操作都必须由机载计算机稳健地执行。**目前，控制模块的设计和调优都是在实际原型车上进行试错。这种方法既耗时又昂贵。在某些情况下，测试不包括整个飞行体验；因此，最终产品可能无法在未见过的真实世界体验中表现令人满意。加拿大国际试飞员学校（ITPS）最近开始开发Long-EZ固定翼飞机的时域仿真模型**，该模型与实际飞行条件非常相似。在将自动驾驶系统部署到实际系统之前，需要在仿真模型上进行调整和验证。如果实施得好，这种方法将大大减少只使用实验进行大规模调整和验证的需要，并显著提高有人驾驶飞机和无人机的安全性和可靠性。这个项目的成果将极大地帮助公司提高其产品在全球的适销性，并加强与潜在客户的合作。在这种情况下，该项目将加强相关**加拿大公司的竞争力，并有助于拓宽其国际市场。他们产品销售的任何增加都被认为是加拿大出口的增加。通过这个项目的合作和未来的长期合作，可以为加拿大做出重大贡献。

Unmanned aerial vehicles (UAVs) have been extensively employed for various critical military and civilian**applications in the last decade, such as surveillance, border patrol, search and rescue, remote sensing and**geographic sampling, forest fire detection and fighting, power-/pipe-line inspection. To make UAVs safer and**more suitable for an increasing number of potential applications, the reliability and survivability of UAVs are**becoming the paramount concern. Compared to manned aerial vehicles, control of UAVs is more challenging -**all flight control, navigation and guidance operations must be robustly carried out by an onboard computer.**Presently, the design and tuning of control modules are done by trial-and-error on actual prototype vehicles.**This approach is time-consuming and costly. In some cases, the tests do not cover the entire flight experience;**thus, the final product may fail to perform satisfactorily during unseen real-world experiences. The**International Test Pilots School (ITPS) Canada has recently started to develop a time-domain simulation model**of the Long-EZ fixed-wing aircraft that closely resemble actual flight conditions. The autopilot system is then**required to be tuned and verified on the simulation model before it is deployed on the real system. This**approach, if implemented well, will greatly reduce the need for extensive tuning and validation using**experiments only and significantly increase the safety and reliability of both manned aircraft and UAVs. The**outcome of this project will significantly help the company improve their product marketability worldwide and**strengthen their cooperation with potential customers. In this case, this project will strengthen the relevant**Canadian companies' competitiveness and help to broaden their international market. Any increased sale of**their products is considered as an increase in Canadian exports. Through this project collaboration and future**long-term collaborations, significant contributions to Canada can be achieved.
