Basically, you should view the fuzzy controller as an artificial decision maker that operates in a closed-loop system in real time. It gathers plant output data y(, compares it to the reference input r(t, and then decides what the plant input u(t should be to ensure that the performance objectives, will be met 1010 Basically, you should view the fuzzy controller as an artificial decision maker that operates in a closed-loop system in real time.
