The decoder determines the optimum conversion ratio to improve the efficiency of system from the relation between the input and output voltage.
首先采用译码器对输入和输出电压进行判比，确定最优的转换系数，提高了系统的效率。

By studying the relation among the system variables and the disturbance response of output, corresponding relation between input and output was changed during the control system design.
In transfer function models these equations are transformed and variables are eliminated between them to find the relation between selected input and output variables.
