Through the characteristic parameters, the system's real-time moment of inertia is given. Then golden section adaptive control law and logic derivative control law both based on moment of inertia are designed. The two kind of control laws are combined to control the attitude of spacecraft and their simulation results are compared with the ones of PD control law which is designed based on the certainly-known system model. The results show that this adaptive control law is effective on the kind of time-variable system studied in this paper.

货币学派主张，在长期只有货币供给会对经济增长产生影响，而政府支出几乎不起作用；与之相反，凯恩斯主义者则指出，一国的财政政策尤其是政府支出能够对宏观经济产生深远的影响，但货币政策却收效甚微。

An S-shape acceleration/deceleration control model is developed by summation progression and the corner of two conjoint lines is adopted as a parametric variable to control the feedrate through the inflexion of two lines. Based on these, interpolation process is divided into two steps: interpolation pretreatment and interpolation point calculation. Feedrate planning is accomplished in the pretreatment step. Interpolation point calculating only depends on the real-time feedrate and the direction vector of the line.
