Combining the qualitative knowledge and quantitative mathematical information of system, the approach provides good control over the nonlinear time varying system with wide variation of parameters.
该方法充分结合系统的定性知识和定量数学描述信息,实现了参数大范围变化时变系统的良好控制。

The variation of single factors, qualitative or quantitative, is simulated by fuzzy functions.
每个定性或定量的单因素变化,采用模糊函数来模拟。
