Population growth and transportation energy needs in Indonesia continue to
increase, while the use of fossil fuel vehicles exacerbates pollution and relies on
non-renewable resources. Electric cars are an environmentally friendly solution
because they do not produce exhaust emissions. PWM is the process of comparing
a carrier signal and a modulation signal to produce a square signal with varying
pulse widths. The pulse width is set by the duty cycle, which determines the ratio
between high and low signals. The greater the duty cycle, the higher the average
voltage produced. This research aims to design and analyze a 2000 W Brushless
DC (BLDC) motor control system using Pulse Width Modulation (PWM) method
based on Proportional-Integral (PI) controller. The system was developed in the
PSIM simulation environment with an input voltage of 48 V and tested both without
load and with a load of 0.24 Nm. Simulation results show that proper setting of Kp
and Ki parameters on the PI controller is able to keep the motor speed close to the
reference value ranging from 600 to 800 rpm stably, both under no-load and load
conditions. The system response shows stability, minimal overshoot, and fast rise
time, indicating that the implementation of the PWM method and PI controller is
effective in regulating the BLDC motor speed. This research contributes to the
development of efficient electric motor control systems suitable for application in
electric vehicles and industrial automation systems.
