Implementation of Mamdani Type FIS and PI Based 3-Legged VSI Controller for an Asynchronous Generator (AG)

In this manuscript, PI and Mamdani type FIS controllers (one for ac generated voltage control and another for dc capacitor voltage control) are recommended to formulate template based algorithm for yielding reference supply currents. The recommended controller controls both reactive and active (kW) power parallel of an asynchronous generator (AG) for keeping the voltage and frequency at the desired level under varying loads. The designing part of 3legged VSI controller is also elaborated. In this manuscript, the simulated outcomes of the performance characteristics are accomplished using both PI and Mamdani type FIS based controller just to testify that the recommended controller is superior to the PI method and is well suited for power generation in isolation mode. Here, the whole electrical system and the controller are modeled using Simpower system and Fuzzy logic toolbox of MATLAB software package.
