Nonlinear Adaptive Control of Long-EZ Fixed-Wing Aircraft

在过去的十年中，无人机（UAV）已被广泛用于各种重要的军事和民用应用，如监视，边境巡逻，搜索和救援，遥感和地理采样，森林火灾探测和灭火，电力/管道检查。为了使无人机更安全，更适合于越来越多的潜在应用，无人机的可靠性和生存能力正在成为最重要的问题。与载人飞行器相比，无人机的控制更具挑战性-** 所有飞行控制，导航和制导操作必须由机载计算机可靠地执行。目前，控制模块的设计和调整是通过在实际原型车辆上进行试错来完成的。这种方法既费时又费钱。在某些情况下，测试并不涵盖整个飞行体验;** 因此，最终产品在看不见的真实世界体验中可能无法令人满意地表现。* * 加拿大国际试飞员学校（ITPS）最近开始开发Long-EZ固定翼飞机的时域模拟模型 **，该模型与实际飞行条件非常相似。自动驾驶仪系统在部署到真实的系统之前，需要在仿真模型上进行调整和验证。这种方法如果实施得好，将大大减少仅使用 ** 实验进行广泛调整和验证的需要，并显着提高有人驾驶飞机和无人机的安全性和可靠性。该项目的 ** 成果将大大帮助该公司提高其产品在全球的市场销售能力，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，并有助于扩大其国际市场。* * 其产品的任何销售增加都被视为加拿大出口的增加。通过这一项目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.
