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 ?
Thanks

ones is a standard MATLAB function for creating an array of ones. There is no function twos, so of course you will get an error. To define an input level of 2, simply do: 2*ones(1000,1)
