Hi all,
I want to create a PID controller for my non-linear arx model but I was told that I needed to linearize my system first. Now I know the PID tuner automatically linearizes it but it does this at the first second at an input level of 1.
My plant has a dead zone behaviour at the first second and also, the input must be a minimum of 2.5V to get it to move from an output of zero.
How do I go about linearizing this non-linear arx plant at these specific conditions ?

Please take a look at this video and try to follow the same approach.
