A simple modelling strategy for integer order and fractional order interval type-2 fuzzy PID controllers with their simulation and real-time implementation

作者：

Highlights：

• A simple strategy is proposed for the modelling of IT2 fuzzy PID controller.

• The modelling is done using 1D input space and without any AND or OR operator.

• The new modelling strategy is extended to fractional order IT2 fuzzy PID controller.

• Applicability of the controllers is depicted through simulation and real-time.

• Usefulness of the controllers is shown through system performance comparison.
