摘要
有些施动系统的转动惯量GD2（或Tm）往往是随着环境和时间而缓变或剧变的，势必影响系统的性能乃至稳定性，当将此扰动作为输入量处理时，系统模型是非线性的，又给系统设计带来了困难，本文提出一种非线性系统的线性控制方法，并由经典控制理论给出了初步的证明。本方法从改造系统的固有特性入手，使系统的实际参数变化不表现在外特性上，实验表明，在Tm大范围扰动时（Tmax/Tmia-28）控制效果令人满意，文中给出了大量的仿真结果。
The rotating inerta GD2 （or Tm） of a drive system is often changed slowly or rapidly according to different time and conditions. It will affect the performances, even the stability, of the system. If this disturbance is considered as a disturbance input, the system is nonlinear, which makes the system design difficult. In this papar, a new linear control method for the nonlinear system is proposed, and a proof to the method in view of the classical control theory is given.this method solves the problem by changing the natural property of the controlled nonlinear systern into that of a linear system, which makes input-output property of the controlled system unchanged when Tm changes. In this papar, a g reat number of simulation results are g iveng and the effects are shown very satisfactory when Tm is changing within a great range （e.g.T max/Tmain=28）.
