Analysis and testing of DC motor control system for electric bike

Abstract

The proposed electric bike is driven by using a 24V350WDC motor and VRLA 24V battery as a source of voltage. Input point settings are done by pressing the speed control button in the form of digital data, which is then converted to voltage by the microcontroller. The output of the microcontroller in the form of a PWM becomes input for the motor driver, where the output speed of the motor will be detected by the speed sensor. The automation used is the PI method using the Zeigler Nichols 2 tuning formula. The control method using PI had been analyzed and tested, resulting in Kp=3.37 and Ki=0.73. The electric bike has been tested with different loads. The proposed electric bike was successfully controlled and able to be driven with a minimum speed of 5km/h and a maximum speed of 20km/h.

Feedforward and Feedback DC Motor Control Methods of Control Systems

“…When designing a DC Motor Control system, it is important to consider the type of motor and its use case [24,25,26]. When one has chosen a type of motor and its application, the next thing to consider is which parameter should be controlled i.e.…”

Experimental Research and Energy Consumption Analysis of a 350 watt Brushless Electric Motor with LiFePO4 Battery

“…The main component of electric bike is electric motor to convert the electric power into torque, battery to produce the electrical energy, and controller to transfer the electric current from battery to the electric motor [4], [5]. In addition, there are also several additional accessories such as a monitor display, pedal assist sensor, and electric brakes.…”
