To weaken the chatter from the controller, the theory of fuzzy logic was used to modify the discontinuous term. Based on fuzzy logic, a variable structure controller was gotten.

为了削弱控制器所带来的抖振，运用模糊逻辑理论对控制器的不连续项进行了修正，从而得到了一种新的基于模糊逻辑的变结构控制器。

Create a portfolio of opportunities: short-term, long-term, incremental, and discontinuous.

创造组合的机会：短期的、长期的、增强的以及间断的。

An artificial viscous term is introduced in the equation to treat the supercritical flow with embeded shock waves and to eliminate the discontinuous solution.

为了处理超临界流和有冲波情况，我们在方程中引入人工粘性项，以消除解中可能出现的不连续性。
