If “Uino” is from Ladin, it means wine.

PID temprature controllation can be replaced by Gaggiuino, which is a system based on MCU(STM32)

Table of Contents

EXPECTATION

  • No broken to the original box of Milesto EM-18
  • No steam for Latte as the principle
  • Keep the original 420cc brass boiler, but with a new PID temp detector and controled by Gaggiuino system
  • Keep the original single vibrating pump(Dec 06, 2023), but controled by Gaggiuino system
  • Replace the time counter with a new LCD
  • Add function of pre-infusion

Defination

  • PID:

    • p: 比例proportion
    • i: 积分integral
    • d: 差分differential

    PID控制需要以满足闭环控制系统作为前提, 其次PID才是精髓, 即结合当前误差比例控制, 历史误差积分求和, 误差变化微分 三者的权重比例进行调节的控制方法
