Performance Studies of Fuzzy Logic Based PI-like Controller Designed for Speed Control of Switched Reluctance Motor

Switched reluctance motor (SRM) has gained significant interest in the field of industrial drive. The controller used to drive the machine is conventional PI controller. But the machine characteristics are very much nonlinear. This poses a problem for conventional controller design as regards to maintaining steady performance. There is also a need to adapt to the variable operating conditions. Fuzzy logic based heuristics is prospective since the exact analytical modelling of the system is difficult. PC implementation of the controller offers great flexibility in both design and maintenance phase. This work implements a PI like fuzzy logic controller (FLC) for SRM, which is found to work successfully in real time conditions. The work compares the performance of the FLC with respect to the conventional PI controller
