给出了电液比例控制规律；利用状态反馈线性化及二次型性能指标线性最优控制方法分别设计了系统跟踪控制飞机位移与速度以及跟踪控制带轮转角与角速度的非线性控制规律；对所设计的拦阻系统进行了鲁棒性分析及拦阻过程仿真，仿真结果表明，通过选取适当比例系数或控制权系数，两种控制系统的控制效果及鲁棒特性均优于新型飞机拦阻系统。 - In the second methodology , parameterized matrices are taken as the weighting matrices of the quadratic performance index . due to the existence of the relationship between parameterized matrices and control forces , the parameterized coefficients of the weighting matrices can be regarded as the control parameters , and they are taken as one part of the synthesis design variables . since the experimental conditions can not meet the requirement of acoustic measuring , a method based on experiment and simulation analysis is developed
在第二种方法中，以参数化矩阵作为二次型性能指标中的权矩阵，由于参数化权矩阵与机构控制力之间存在的对应关系，可以将权矩阵的参数化系数作为控制系统参数，与结构设计参数一起同时作为独立的设计变量，对目标函数进行优化分析。
