摘要
针对滚筒式炒菜机的锅体、叶片和倾倒动作的快速响应和平稳运行,设计了一种以STM32F767IGT6为主控制器的多电机协同控制器。采用74HC244隔离电路和双BTN7960芯片电机驱动电路实现电机控制,增量式编码器和光电耦合器测速电路实现速度反馈,PID算法实现速度的整定。试验表明,设计的多电机协同控制器能够实现电机的快速响应,电机在0.04~0.06 s稳定到预设速度,锅体、锅铲、倾倒控制电机可以实现同步和独立工作模式,并且相互影响可以忽略,满足炒菜机的动作需求。
Aiming at the quick response and smooth operation of the pan body,blade and dumping action of the drum-type cooking machine,a multi-motor cooperative controller with STM32 F767 IGT6 as the main controller is designed.The controller adopts 74 HC244 isolation circuit and dual-BTN7960-chip motor drive circuit to realize motor control,incremental encoder and photocoupler speed measurement circuit to achieve speed feedback,and PID algorithm to achieve speed setting.The experiments show that the multi-motor cooperative controller can realize the fast response of the motor.The motors stabilize to the preset speed in 0.04~0.06 s.The pan body,blade,and dumping control motors can achieve synchronous and independent working modes,and the interaction is neglectable.This controller can meet the action needs of the cooking machine.
