In this paper we design a fuzzy adaptive internal model control for the speed varying problem of a PMSM. The PMSM under the vector control model is studied. The designing of the fuzzy adaptive IMC involves three steps. First a standard internal model controller is designed. This model has high input saturation. A modified IMC is designed which reduces the input saturation. The variation of inertia at the load end is reduced by designing a Fuzzy based adaptive IMC. An Indirect Matrix Converter is provided at the power supply end for the better controllability of the speed regulation of the PMSM.
