Abstract—This paper describes an improved method for controlling speed of Brushless DC motor (BLDC). Internal Model Control (IMC) method is used to achieve the good characteristics such as robustness, easiness, flexibility and stability. Here, this novel idea uses the steady-state DC model instead of BLDC’s or general DC’s to reduce large amount of calculation but it still achieves positive features of IMC method. To challenge the robustness, the proposed method is performed with not only nominal parameters but also large change of plant’s parameters. On MatLAB Simulink, the obtained results show that the output signals well respond the referred signals. To be more objective, our results are compared with 2 previous approaches.
