Abstract

The optimal linear quadratic regulator (LQR) method is a powerful technique for designing controllers for complex systems that have stringent performance requirements. For most realistic applications, the LQR problem must be solved via a computer aided design (CAD) package such as MATLAB. With the CAD packages solving the optimization problems, the challenge lies in how the weighting matrices are chosen. With experience, practising engineers become quite adept at choosing these matrices for a specific application. Students in a typical quarter or semester long course do not have the luxury of this experience. Consequently, the authors have written a MATLAB graphical user interface (GUI) that allows the students to easily tune the weighting matrices and immediately see the consequences of those changes. This paper describes the motivation behind the LQR Design GUI, the GUI construction process, and the use of the LQR Design GUI in the senior-level modern control systems course at the U.S. Naval Academy.

一个MATLAB图形用户界面，用于线性二次控制的设计

最优线性二次型调节器(LQR)方法对于设计对性能要求严格的复杂系统的控制器是一种强有力的技术。对于大多数实际应用，必须通过计算机辅助设计(CAD)软件包(如MATLAB)来解决LQR问题。随着CAD软件包解决优化问题，挑战在于如何选择加权矩阵。随着经验的积累，实践工程师在为特定应用选择这些矩阵方面变得相当熟练。在一个典型的季度或学期的课程中，学生没有这种奢侈的经历。因此，作者已经编写了一个MATLAB图形用户界面(GUI)，允许学生轻松调整权重矩阵，并立即看到这些变化的后果。本文描述了LQR设计GUI背后的动机，GUI的构建过程，以及在美国海军学院高级现代控制系统课程中使用LQR设计GUI。
