自平衡莱洛三角形 RGB版 HW:Ver 1.5 FW:Ver 1.2.1
|
||
立创EDA https://oshwhub.com/muyan2020/zi-ping-heng-di-lai-luo-san-jiao_10-10-ban-ben_copy
|
||
RGB版本程序 https://gitee.com/muyan3000/RGBFOC 基于45°(https://gitee.com/coll45/foc/)程序修改
|
||
arduino开发环境-灯哥开源FOChttps://gitee.com/ream_d/Deng-s-foc-controller，并安装Kalman。
|
||
|
||
FOC引脚32, 33, 25, 22 22为enable
|
||
AS5600霍尔传感器 SDA-23 SCL-5 MPU6050六轴传感器 SDA-19 SCL-18
|
||
本程序有两种平衡方式， FLAG_V为1时使用电压控制，为0时候速度控制。电压控制时LQR参数使用K1和K2，速度控制时LQR参数使用K3和K4
|
||
在wifi上位机窗口中输入：TA+角度，就可以修改平衡角度
|
||
比如让平衡角度为90度，则输入：TA90，并且会存入eeprom的位置0中 注：wifi发送命令不能过快，因为每次都会保存进eeprom
|
||
在使用自己的电机时，请一定记得修改默认极对数，即 BLDCMotor(5) 中的值，设置为自己的极对数数字，磁铁数量/2
|
||
程序默认设置的供电电压为 12V,用其他电压供电请记得修改 voltage_power_supply , voltage_limit 变量中的值
|
||
V1默认PID针对的电机是 GB2204 ，使用自己的电机需要修改PID参数，才能实现更好效果
|
||
V2电机是2715
