| 中文摘要 |
| 本文给出了LQP中Q阵选择的一种逆算法，此法既解决了试凑法的盲目性，又避开了解Riccati方程的繁琐计算，只须进行多项式运算。用此法设计线性调节器，可使闭环系统即具有希望的极点配置，又具备最优性。
在Φ300mm四辊可逆冷轧机板形板厚综合最优控制系统的设计中采用逆算法，由计算机仿真和微机模拟试验结果表明，理论与实际相符，系统具有良好的动态性能，控制精度达1/1000~1/10000。 |

| This paper gives an inverse method for selecting weighting matrices in LQP. The method enables us to avoid blindness of trial as well as avoid solving complicated Riccati matrix equation, and needs only to calculate polynomials. The system designed with the inverse method is optimal and has desirable closed-loop poles. Then the inverse method is applied in the design of the plane and gage synthetical optimal control system of Φ300mm and four rolls cold strip mill, simulation tests by microcomputer show that theory is in keeping with practice, system’s transient property is fine and system is accurate with 1/1000 to 1/10000. |
