Interval Type-2 Fuzzy Logic Controller for Speed Control of DC Motor in an Intelligent Manner

Abstract

The method of variable speed control use in direct current motors adopting a fuzzy logic controller is fast replacing as compare some of the earlier conventional methods. In Electrical drive system a dc motor is fed from a fully controlled single phase convertor but the control is fails in the uncertain condition. This type of problem makes a critical issue in power plant where lots of motor are working. So, there is need to control dc motor in such uncertain condition. This work gives a design based on simulation of intelligent control by Interval Type-2 Fuzzy Logic Controller (IT2FLC). The designed fuzzy controller is effective in control performance in abnormal or uncertain conditions. The simulation study has been carried out and result are compared with type-1 FLC. The Result clearly demonstrate the superiority of the IT2FLC and compare to other methods proposed system is capable to control dc motors and performed better in both steady-state and cyclic conditions with more reliability
