Fuzzy Logic Based Control of high current SRM

Abstract

In this paper, the speed and advance angle control method is described to drive an industrial low voltage SRM (Switched Reluctance Motor) for a forklift truck. This method is based on data by the real experiment. The low voltage SRM is difficult to achieve the desired dynamic speed because the rising time of current grows longer. Fuzzy logic is a flexible and general-purposed method of implementing non-linear function and as such it is useful in control applications. Therefore, we designed a fuzzy current controller to control the velocity of SRM appropriately. And this system is used the look-up table for advance angle control. We show that the proposed controller with fuzzy logic and look-up table has good performance for the nonlinear SRM in experiments and simurations.
