利用修正的收益差等式，给出了LQ最优调节器对交叉积项性能指标的保证稳定裕度。给出了保证稳定裕度的充分条件以及标准LQ最优调节器稳定裕度的保证条件。以直流电机系统的LQ最优控制为例，说明了如何选择加权矩阵以保证所需的稳定裕度。>
Suggested are the guaranteed stability margins of LQ optimal regulators for the performance index with cross-product terms, using modified return difference equality. Sufficient conditions to guarantee the required stability margins are presented as well as the conditions to guarantee the stability margins of standard LQ optimal regulators. An example for LQ optimal control of a DC motor system is given to demonstrate how the weighting matrices can be chosen to guarantee the required stability margins. >
