* gimbal.c - 云台双轴控制(串级 PID)
* gimbal.c - 云台双轴控制(串级 PID, 全电流环模式)
* Yaw(2026-09 重写):双陀螺环,见 gimbal.h 与 robot_param.h 说明
* 位置环:err(°) = 目标角 - SIGN*att_deg_yaw -> 目标角速度(°/s,限幅)
* 速度环:err(°/s) = 目标角速度 - SIGN*gyro_z -> 电压(限幅)
* 稳定性条件:SIGN*G>0,G 为"电压->陀螺 z 角速度"的装配增益,
* 速度环:err(°/s) = 目标角速度 - SIGN*gyro_z -> 电流(限幅 ±16384)
* 稳定性条件:SIGN*G>0,G 为"电流->陀螺 z 角速度"的装配增益,
* 由 gimbal_detect_yaw_sign() 上电实测,彻底消除双传感器符号打架
* Pitch:位置环用 QEKF Roll(安装方向),速度环转子转速(legacy 案,无符号史问题)
* 发送:CAN2 0x1FF 槽1=Yaw 电压;CAN1 0x1FF 槽2=Pitch 电压,槽3=拨弹电流
* Pitch(电流环重整):位置环陀螺 Roll -> 期望转速(RPM), 速度环转子转速 -> 电流(限幅 ±16384)
* 发送:CAN2 0x1FE 槽1=Yaw 电流; CAN1 0x1FE 槽2=Pitch 电流; CAN1 0x1FF 槽3=拨弹电流
