讨论一类在特定时间消费的物品的销售控制策略。
The problem of sale control strategy for products consumed in a specified time is studied.
在本文使用的控制策略中，并联部分由PI控制和定时滞环比较PW M控制组成，而串联部分的控制则采用三角载波调制的PWM控制。
The parallel part control consists of a Proportion-Integral (PI) control and a regular time hysteresis PWM control. The Series part control adopts a triangle wine-linear PWM control.
实验结果表明：采用输入指令整形减振技术和压电陶瓷相结合的抑振策略，系统稳定时间缩短80%以上，双重驱动的抑振策略实现了高速高精度的运动控制。
Experiments validate that the stabilizing time is reduced by 80%. The dual drive strategy is an excellent way to realize high speed, high precision motion control.
