Hi Guys,
i have a problem with my control. i want to use a pid controler with constant parameters for the proportional and the integral parts. The derivative part is prepared in an lookup-table. i have no idea how to connect the output of the lookuptable und the pid-controler. do i have to build up the pid-controler on my own or can i use the given one and just change some properties to get another input-channel.
thanks for your answers greetings Lucki

I recommend building your PID block, it should take you only a few blocks. A Sum, an Integrator, a Transfer Function, a few Gains, add lookup for the gain "scheduling" you describe and everything should be all set.
A trick to get you started: Look under the mask of the shipping PID block, it will show almost everything you need.
