Choosing the proper state weight matrix Q in the LQ index by the system parameters, we can express the state feed-back solution of the LQproblem in the form of the output feedback.
根据系统参数，在二次型指标中适当选择状态加权矩阵q可以将LQ问题的状态反馈解表成输出反馈的形式。

Besides, the LQ theorem presented in this paper can be used to change a nonlinear single regression problem to a linear one by means of transformation of variables.
