Realization of nonlinear and liner PID controls using simplified indirect inference method

摘要

This paper deals with a practical method for the realization of nonlinear and linear PID controls using fuzzy control methods. In this method, not only nonlinear PID control but also linear PID control can be easily realized by applying the simplified indirect inference method to the fuzzy control rule. Therefore, it is first shown that nonlinear PID control based on the PID controller can be realized using this method. Secondly it is shown that linear PID control can also be realized simply by replacing an arctan type with a line type in the antecedent part of the fuzzy control rule.
