在Maple平台上应用最小二乘法估算动力学参数

以大量实验数据为基础在Maple平台上运用最小二乘法,估算了气相苯加氢反应中反应速率常数及苯的吸附平衡常数,结果较为满意;并且估算了CO与Cl_2在活性炭表面上催化合成光气的反应中动力学的最优参数,计算值与实验值的最大相对误差不超过5%;最后推算了NO与H_2反应的反应速度方程式,计算值与文献值很相似。应用这种方法既克服手工计算的繁琐、工作量大的缺点,还能提高计算的精度,大大地方便了化学反应速率式的确定。

Analytical solutions to the matrix inequalities in the ILF control-observer scheme for non-cooperative rendezvous with unknown inertia parameters

ABSTRACT

In this paper, the problem of robust control for non-cooperative rendezvous is investigated based on implicit Lyapunov function (ILF) method. The dynamical model of relative motion between two spacecrafts is established in the body coordinate system of the chaser spacecraft without using the target-orbital information. In view of unknown inertia parameters and external disturbances, an ILF control-observer scheme is introduced, where the ideal controller is first designed and then estimated by the observer. The closed-loop system is proved to be finite-time stable, and the controller and observer gains are, respectively, obtained by solving linear matrix inequalities and parameterised nonlinear matrix inequalities. To reduce the computational burden, analytical solutions to these matrix inequalities are provided. The effectiveness of the theoretical results is demonstrated by simulation examples.
