Based advanced controlling strategy now, self-adapting fuzzy PID controller is designed. Simulated with MATLAB/Simulink, system responses tracking step signal, square wave signal, sine signal, triangle signal and saw tooth signal are reproduced.

2结合当前先进的控制策略，针对电液伺服控制径向柱塞变量泵，设计了自适应模糊PID控制器，并通过计算机仿真，再现了系统跟踪阶跃信号、方波信号、正弦波信号、三角波信号、锯齿波信号时的系统响应。

Based on one-cycle control having such merits as anti-perturbation of source, fast dynamic response, robustness, constant frequency, but when converter works in light load its power factor becomes very poor. The modified OCC was proposed, adopting feed-forward compensation control improves influence of power factor at light load, further study adopting independence saw tooth wave completely eliminate influence of power factor at light load.

基于单周期控制有源前端变换器具有抗电源扰动能力强、动态响应快、鲁棒性强、恒频控制等优点，但在轻载时变换器的功率因数变差，提出了改进OCC策略，采用前馈补偿控制改善轻载时对功率因数的影响，进一步研究采用独立的锯齿波电路完全消除轻载时对功率因数的影响，建立改进OCCAFE变换器的数学模型。

Every sub-circuit is designed reasonably according to the principle and character of PWM switching converter, such as: bandgap, error amplifier, oscillator, narrow pulse generator, saw tooth generator, PWM comparator, PWM modulator, output stage, OCP circuit and low voltage comparator.

根据PWM开关电源的原理和特点，合理地设计了各个子电路，其中包括：带隙基准源、误差放大器、振荡器、窄波发生器、锯齿波发生器、PWM比较器、PWM脉冲调整器、输出级电路、过流保护电路和低压比较器等。

Setting the saw at the proper cutting depth keeps blade friction to a minimum, removes sawdust from between the blade teeth, results in cooler, faster sawing and reduces the chance of kickback.

设置恰当的锯深，可以使锯片所受的摩擦力最小，锯齿间不存锯末，可以使切割作业更快，部件温度更低，同时也能减少反冲力。

The factory's main products are various types of sawtooth-jig, play-sand, sand pump, the flotation machine, magnetic separator, the shaker, such as mining mineral processing equipment.

A wide, sage-covered plain, home to bison and moose, stretches across the valley to the base of the jagged Teton Range, which rises abruptly from the valley floor.

一个广阔的，红根草覆盖的平原，是野牛和驼鹿的家园，延伸横过那山谷锯齿状的提顿山脉的底部和那个突然从谷底升起的月亮。

A wide, sage-covered plain, home to bison and moose, stretches across the valley to the base of the jagged Teton Range, which rises abruptly from the valley floor.

一个广阔的，贤能者――覆盖的平原，原产地的野牛和北美大鹿，延伸横跨山谷到到基楚的锯齿状的Teton范围，那突然间上升从山谷底。

The invention of the foot with people similar size is determined by a rectangular wooden, wire or wire into a certain shape and from braking effect of the iron plates with serrated, as well as before and after the wire with a rope through the ring and both sides supporting it firmly to the foot of the tie on which are formed.

本发明与人们脚的大小相仿，是由长方形木板，钢丝或铁丝制作成一定的形状和起刹车作用带锯齿的铁片以及用绳子通过前后钢丝环和两侧的辅助将它牢牢的绑到脚上而组成的。

The right-side image is the antialiased drawing and we can see the smoothing achieved using "GrayScale" intensities.
