Fuzzy Gain Scheduling for Cascaded PI-Control for DC Motor

Abstract

Electric vehicles generally use a permanent magnet DC motor (PMDC). An example of an electric vehicle using PMDC is the electric scooter. The PI Controller to control the electric scooter scheme has a cascade configuration. The common problem in implementing a PI cascade controller is that the gain does not match the increasing error value in some conditions. There is also a case where a cascaded PI control method uses fuzzy logic controller, commonly called fuzzy gain scheduling. The addition of fuzzy gain scheduling on the PI speed controller shows that the speed graph response of the PMDC is better than the speed response without fuzzy gain scheduling. This method can give a good performance.
