Motor Control Algorithms

Mathematical modeling is widely used in software development for motor control systems. This method is indispensable for creating complex technical and technological systems as it enables us to evaluate the performance of developed solutions and choose the best one before any prototypes are even made.

We use mathematical functions, algorithms, and modeling in electric motor control to provide the foundation for future designs that are applied in industrial automation, robotics, the electric power industry, and other areas.

Here are the control algorithms we use in our designs:

Scalar control V/f (Volts per frequency) control
Stepper motor control
SVPWM/SPWM/PWM control
3-phase 6-step control

Vector control

DTC — direct torque control
FOC — field oriented control

Observers

EKFExtended Kalman Filter
ELO Extended Luenberger Observer
LSO Luenberger State Observer
MRAS Model Reference Adaptive System
BEMF Back EMF
Neural network based

FAQ

What is motor control?

Motor control is a set of tools that regulate an electric motor's operation in a specific way. They perform a variety of essential tasks, such as starting and stopping a motor, changing the direction of rotation, choosing and controlling the speed of rotation, regulating the torque, and safeguarding the motor from overloads and faults.

What is a motor controller? How does it work?

Devices called motor controllers are used for controlling how an electric motor operates. They choose whether to rotate in the forward or reverse direction, accelerate, or decelerate, as well as other operating parameters.

What types of motor controllers exist?

There are the following types of motor controllers:

Variable-frequency drive (VFD)/Variable frequency inverter;
Servo drive;
Soft starter;
Multi-axis motion controller;
Stepper motor controller;
DC motor controller;
BLDC motor controller/ Brushless Motor Controller.

What is the difference between BLDS and PMSM motors?

BLDC means brushless DC electric motor; and PMSM is a permanent magnet synchronous motor. They are similar, but each has its own characteristics.
