教我们飞行力学的孙教授，他的研究方向是飞行器控制，我对他的研究很感兴趣，所以加入了他的实验室。
第一次参与科学研究是在大学三年级，我和两位队友组成团队，在孙教授的指导下，参加了学校的科研训练。
我们的项目是一个关于伪谱法得最优控制器，研究时间是十个月。这个控制器运行在嵌入式平台上，用于计算飞行器的飞行轨迹。

研究工作刚开始的时候进行的很慢，因为我们都是第一次研究大型的课题，我们得基础知识不够，而且还有课程表里得其他课程要学习，
所以压力很大。我们学习了数值方法，非线性规划，最优控制原理等基础知识，然后开始阅读相关得文献，了解最新的
研究结果，这些工作花费了四个月的时间。

伪谱法是一种求解非线性最优控制问题的数值算法，是最优控制领域的研究热点。我们的任务是，按照最新的研究结果实现伪谱法。

考虑到项目对快速性的要求，我们选择了C++作为编程语言，利用开源的矩阵库Armadillo作为基础的线性代数库，
参考了开源的最优控制软件gpops，psopt。我们对算法核心进行了改进，使用了最新的RPM方法，并加入了自适应配点算法。

代码有10000多行，重写了两次，最终用了三个月写完。最后得测试结果比现有得matlab版本的实现要快十倍，满足项目要求。在研究过程中，
我们参考和使用了大量的开源软件包，因此我们决定把自己的软件也开源，发布在开源网站上，分享给其他的研究者。

整个研究过程很累，但是我觉得非常值得，因为学到了很多东西。经过自己实践以后，我对微积分、线性代数和最优控制理论有了更深刻的理解。
知道了怎么研究一个实际的问题，以及如何与其他人合作研究。在研究过程中进行学习，知识掌握得最快最好，因为，有一点不懂的话，整个项目就会失败。

Professor teaches us flight mechanics of the Sun, his research interests are aircraft control, I am interested in his research, joined him in the laboratory.Participate in scientific research for the first time is in the third year of University, I and two other members of the team team, under the guidance of Professor Sun, participated in the school's research training.Our project is a pseudo-spectral method on the optimal controller research time is ten months. This controller runs on an embedded platform, used to calculate the aircraft's flight path.Research work is going really slow at the start, because we are all subject of study for the first time, we have enough basic knowledge, but also in other courses from the curriculum to learn,So a lot of pressure. We learned about numerical methods, nonlinear programming, optimal control theory, fundamentals, and then started to read the document, find out about the latestThe results, which spent four months time.Pseudospectral method is a numerical algorithm for solving nonlinear optimal control problems, is the field of optimal control research. Our task is, according to the latest research results implementation of the pseudo-spectral method.In view of the demands for speed, we choose C++ as programming language, using the open source matrix libraries Armadillo as basic linear algebra library,Optimal control of reference to open source software gpops,psopt. We have the core algorithm was improved using the latest RPM, and joined the Adaptive matching algorithm.Code over more than 10,000 lines, overriding the two eventually took three months to finish. Final test results achieved 10 times faster than existing MATLAB version to meet the project requirements. In the process of researching,We refer to and use a lot of open source software packages, so we decided to make our own software is open source, released in open source Web site, shared with other researchers.Throughout the research process is very tired, but I think well worth it, because a lot of things. Through their own practice, and my calculus, linear algebra, and have a deeper understanding of optimal control theory.Know how to study a practical question, as well as how to cooperate with others research. In conducting the study to learn, knowledge is the best and fastest, because, it does not understand, the entire project will fail.

Flight mechanics teach us, Professor Sun, his research interests are in control of the aircraft, I was very interested in his research, so he joined the laboratory.
Scientific research is the first to participate in junior college, my two teammates and a team under the guidance of Professor Sun, he participated in the research training schools.
Our project is to obtain optimal controller on a pseudo-spectral method, the study period is ten months. This controller runs on an embedded platform, used to calculate the flight path of the aircraft.

When beginning work carried out very slowly, because we are the first large-scale study of the subject, we have enough basic knowledge, but also have other courses from the curriculum to learn,
so a lot of pressure. We study the numerical method, nonlinear programming, optimal control and other basic principles of knowledge, and then began to read the relevant literature too, learn about the latest
research results, the work took four months.

Pseudo-spectral method is a numerical algorithm for solving nonlinear optimal control problem, optimal control in the field of research. Our task is, according to the latest findings pseudo-spectral method.

Taking into account the rapid project requirements, we chose C ++ as the programming language, the use of open source matrix library Armadillo as the basis of linear algebra libraries,
reference source optimal control software gpops, psopt. Our core algorithm has been improved using the latest RPM method, and joined the adaptive algorithm with a point.

There are more than 10,000 lines of code, rewritten twice, finally took three months to finish. Finally, get the test results obtained than the existing version of the matlab achieve faster times to meet project requirements. During the research,
we refer to and use a lot of open source packages, so we decided to have their own open source software, open source posted on the website, share it with other researchers.

Throughout the study tired, but I think well worth it, because a lot of things to learn. After a practice myself, I calculus, linear algebra and optimal control theory have a more profound understanding.
We know how to study a real problem, and how to cooperate with others to study. Research carried out in the course of learning, knowledge mastery of the fastest and best, because, a little do not understand, the whole project will fail.
