Enhancing the Step Response of Hybrid Stepper Motors %K Hybrid stepper motor %K Fuzzy controller %K PID controller %K Genetic Algorithm %R 10.21608/asat.2011.23288 %X In this paper, the basic differential equations of hybrid stepper motor are used to build up a model using MATLAB software package. The implementation of fuzzy logic (FL) and proportional-integral-derivative (PID) controllers are used to improve the step response of the hybrid stepper motor. The numerical simulations by a PC-based controller show that the PID controller tuned by genetic algorithm produces better performance than tuned by fuzzy controller. Fuzzy PID-like controller gives better performance than the other linear fuzzy controllers. Finally, the comparison between PID controllers tuned by genetic algorithm and fuzzy PID-like controller shows that, the fuzzy PID-like controller produce better performance. %U https://asat.journals.ekb.eg/article_23288_6612ed7c12750768a939775033a1d68e.pdf
