BLDC motor is one of the electric drives that is widely used for several purposes, such as electric vehicles, aerial robots, and underwater vehicles. Given the many uses of BLDC motors, a control method is needed that can increase the utility of this electric drive. This study used two Brushless DC motor (BLDC) driven by the driver used on electric vehicles. As controller, this study is using Arduino Mega microcontroller. <br /> <br /> <br /> In this research, the method of sliding mode control (SMC) with a modification of two-steps LMI approach will be implemented to control the speed of BLDC motor. This method is applied with the assumption that the system used is linear time-invariant (LTI) and continuous. This method also ensures that the closed loop system with the controller is stable in the sense of Lyapunov. <br /> <br /> <br /> The results of this study indicate that the design result of SMC controller: two-steps LMI approach is as expected. The simulations performed with MATLAB have resulted in a stable system response and can track the input given. Likewise, the results of the implementation of BLDC motor have shown a same result as the simulation, but with some errors that can be produced from sensor errors, filters, and the system models. <br />
