can you check if this wrapper for luisllamasbinaburo/Arduino-PIDController-Library can help you ?
So, only had to tweak your b4r BasicPIDController sample project for my setup and scale the analog input and digital output to be in the 0 to 255 range - it works perfectly! Well done and thank you very much for this great wrapper. Lots for me to learn from it.

Attached is my sample B4R project making use of your library - your library works very well!

B4R Code:
#Region Project Attributes
    #AutoFlushLogs: True
    #CheckArrayBounds: True
    #StackBufferSize: 600
#End Region
