So a p - fuzzy two - mode controller bring out . simulation results illustrate that the proposed controllers are effective in suppressing the maximum overshoot and in reducing the decaying oscillation cycles and also superior then pid controllers 仿真结果证明，本文所提出的控制策略在抑制超调、减少震荡周期、提高系统的稳定性上都得到提高，优于单纯常规pid控制。

Recent progress in ultrafast optics has allowed the generation of ulfcraintense light pulses comprising merely a few field oscillation cycles . the arising intensity gradient allows electrons to survive in their bound atomic state up to external field strengths many times higher than the binding coulomb field and gives rise to ion - ization rates comparable to the light frequency resulting in a significant extension of the frontiers of nonlinear optics and ( nonrelativistic ) high field physics 随着超快光学技术的发展，仅含几个振荡周期的超强脉冲已经能产生，且其强度梯度可使电子存在比库仑束缚场高许多倍的外场产生的原子束缚态上，并产生了同光频相差不大的电离率，从而促进了非线性光学前沿及非相对论的强场物理的延伸。
