The selection of weight matrices in linear quadratic optimal control needs a lot of experience and skills. 二次型最优的权矩阵选择是一个包含大量经验与技巧的问题。
In LQ optimal control design, the appropriate weighting matrices will lead to a better state feedback matrix, thus forming a closed-loop system with satisfactory performance. 在线性最优控制器的设计过程中，选择合适的权矩阵，可以产生较好的反馈阵，从而设计出具有良好性能的闭环控制系统。
