I had worked a week on using Control_Surface.h to DYI a (Mackie Control Universal) MCU MIDI CC controller: 3 buttons for play,record and stop. also have 3 slider potentiometers, for semding midi cc control change message(CC1,CC3,CC11).
the buttons are ok now . but the slider potentiometers just can not work.
anyone here please help me out of that, I'll be appreciate.

Did you try a simple analogRead() sketch to prove that your slide pots were wired correctly? The software can't do anything without the hardware working.
The following picture is my wiring diagram, because I failed to successfully upgrade the firmware of Uno Mini so I chose to use Teensy4 . and also have some data which is from using “Mackie-Control-universal-reverse-Engineering.ino” on Reaper. these data should be similar to the using USBMIDI_Interface USBMIDI, right? and I can't tell which instruction is used to control the MIDI CC controller.
Please help me to figure it out?! Thank you very much！

The control change messages for the V-pots only get sent from the controller to the DAW, so you won't see them in the output from the sketch you posted, which only prints incoming messages.
If you want to see the outgoing messages, you'll have to add a USBDebugMIDI_Interface or USBDebugMIDI_Output.
Looks like the wiring is correct and you get the right MIDI messages.
If your DAW doesn't understand them, then you'll have to either configure it differently, or send different messages from the Arduino.
As mentioned earlier, if you're using the MCU protocol, you cannot use potentiometers, you need incremental encoders. (Only the motorized volume faders are potentiometers on a Mackie Control Universal.)
