Abstract
This paper investigates the application of new fuzzy
adaptive controller to the control of permanent magnet synchronous
motor (PMSM) speed. The proposed controller consists
of two parts: the first one, is the classical fuzzy logic controller
(FLC) constituted by fimy If-TheB rules, whose inputs
are the speed error and the change of speed error, and its output
is the reference torque. The second part, is the adaptation
mechanism, which adjusts the Fuzzy controller parameters to
minimize the error between the reference speed output and the
machine speed. The fumy adaptive controller PAC) can be
started without prior information on the machine, and can
learn and tune rapidly the fuzzy controller rules to meet the
desired performance, even when the machine parameters
change. A simulation studies for various operating conditions,
show the superior performance of the FAC compared to PI
controller.
