You've mixed up direct acting and reverse acting controllers. A flow control with a valve regulating the flow is a typical example for reverse acting control. If the flow is low (PV < SP), the controller opens the valve more, i.e., it increases the OP. A back pressure control is an example of a direct acting control, e.g., if the pressure is too low (PV < SP), the controller would try to close the valve so that the pressure behind it could build up, i.e. the OP goes down.
Please also make a video for PI and PID logic to control. Multiple Devices like Inverters analog output with static and dynamic setpoint output as per requirement

Nicely Explained
Thanks for liking
good illustration, it would be great if you controlled a physical system and tune the PID parameters, thank you

Thank you very much for this video :D
Always happy to help.
