Controllers are classified into digital and analog versions. The main difference between a digital DC motor controller and its analog variant is that the former comprises microcontroller (MCU) based hardware and firmware. 

This example will show how to model a DC motor's speed using different approaches in Collimator. The three approaches involve simulating diagrams from a differential equation, a transfer function, and a state variable model. Then, we will design and simulate a PID controller for the DC motor speed.

Motor power relies on the current supplied by the power source. Thus, a low-power BDC motor needs a low current controller and vice versa. A high current DC motor controller typically uses a switching regulator. 

In my case, I chose to collect the required data manually. This is straightforward if you have a regulated power supply (RPS) or similar power supplies and a multimeter. Here is the data I collected:

Digital control is used to create square wave. This pattern can vary voltages between full on i.e. 5V and full off i.e. 0V. The duration of on time i.e. when the the signal is present is known as pulse width. PWM waves for the different duty cycles are shown in the figure below.

The code should be easily ported to any other STM32 microcontroller or reconfigured to use any Timer and PWM Channel that you want just as we’ll see in this section. And here is a link for the course’s repo, and you’ll find the DC_MOTOR driver in the ECUAL directory as usual.

In this article, we’d like to share our own experience in the design and implementation of a brush DC motor controller. You’ll also learn about challenges you can meet if you decide to build it yourself.

I used 12V high torque DC motor which I powered using there 3.7V Li-ion batteries connected in series which give around 12V. So now using the potentiometer we are able to control the speed of the DC motor, or the PWM signal produces by the 555 Timer IC.

Once the distance is calculated, the move_motors function is called, and the distance is passed as an integer parameter. Just like in Demo 2 Version 2, motors are moved in one of two ways: if distance is 50cm or less, the motor speed is proportional to the distance.

Three wires are needed. Insulated wires work best as they prevent wires from crossing and the battery from short circuiting.

Implementation of vector control requires intensive mathematical processing, including the ability to rapidly solve the trigonometric functions needed to convert the coordinate space.

PWM is a method through which we can generate variable voltage by turning on and off the power that’s going to the electronic device at a fast rate.

Compliance with the system requirements is the basic principle you should follow while selecting components for your DC motor controller schematic. This relates to an MCU, gate drivers necessary to control the transistors, and other components.
