Fuzzy logic controllers have been emerged as one of the most active and useful research areas in the field of fuzzy control theory. That is fuzzy logic controllers haven successfully applied for controlling various physical processes.
This paper shows how fuzzy logic is used for position control application. Three types of Fuzzy Controllers are implemented and their position control response is measured. Two of them are FPI, FPD with two inputs (e ,∆e). The third controller is build via connecting the first two in parallel. Two dimensional rule bases, with seven memberships for both inputs and output, are used to perform the control action. Computer simulation is guided to illustrate the performance and show the result for the three types.
