Design of optimal membership functions for fuzzy gain-scheduled control

The design of optimal membership functions for model-based fuzzy gain-scheduled control is addressed. The antecedent membership functions in the controller are computed such that the closed-loop behavior complies with the specifications over the entire operating range. It is shown that better performance is obtained than with the standard Parallel Distributed Control (PDC) approach, which is based on using the model membership functions in the controller. A real-world application example of aircraft gain-scheduled control is presented.
