Get Started with Motor Control Blockset

Design and implement motor control algorithms

Motor Control Blockset™ provides reference examples and blocks for developing field-oriented control algorithms for brushless motors. The examples show how to configure a controller model to generate compact and fast C code for any target microcontroller (with Embedded Coder®). You can also use the reference examples to generate algorithmic C code and driver code for specific motor control kits.

The blockset includes Park and Clarke transforms, sliding mode and flux observers, a space-vector generator, and other components for creating speed and torque controllers. You can automatically tune controller gains based on specified bandwidth and phase margins for current and speed loops (with Simulink® Control Design™).

The blockset lets you create an accurate motor model by providing tools for collecting data directly from hardware and calculating motor parameters. You can use the parameterized motor model to test your control algorithm in closed-loop simulations.

Run 3-Phase AC Motors in Open-Loop Control and Calibrate ADC Offset

Run 3-Phase AC Motors in Open-Loop Control and Calibrate ADC Offset

Uses open-loop control (also known as scalar control or Volts/Hz control) to run a motor. This technique varies the stator voltage and frequency to control the rotor speed without using any feedback from the motor. You can use this technique to check the integrity of the hardware connections. A constant speed application of open-loop control uses a fixed-frequency motor power supply. An adjustable speed application of open-loop control needs a variable-frequency power supply to control the rotor speed. To ensure a constant stator magnetic flux, keep the supply voltage amplitude proportional to its frequency.

Six-Step Commutation of BLDC Motor Using Sensor Feedback

Six-Step Commutation of BLDC Motor Using Sensor Feedback

Uses 120-degree conduction mode to implement the six-step commutation technique to control speed and direction of rotation of a three-phase brushless DC (BLDC) motor. The example uses the switching sequence generated by the Six Step Commutation block to control three-phase stator voltages, and therefore, control the rotor speed and direction. For more details about this block, see Six Step Commutation.

Field-Oriented Control of Induction Motor Using Speed Sensor

Implements the field-oriented control (FOC) technique to control the speed of a three-phase AC induction motor (ACIM). The FOC algorithm requires rotor speed feedback, which is obtained in this example by using a quadrature encoder sensor. For details about FOC, see Field-Oriented Control (FOC)

Field-Oriented Control of PMSM by Using Hall Sensor

Implements the field-oriented control (FOC) technique to control the speed of a three-phase permanent magnet synchronous motor (PMSM). The FOC algorithm requires rotor position feedback, which is obtained by a Hall sensor. For details about FOC, see Field-Oriented Control (FOC).

Field Oriented Control of PMSM by Using SI Units

Field Oriented Control of PMSM by Using SI Units

Implements the Field-Oriented Control (FOC) technique to control the speed of a three-phase Permanent Magnet Synchronous Motor (PMSM). However, instead of the per-unit representation of quantities(for details about the per-unit system, see Per-Unit System), the FOC algorithm in this example uses the SI units of signals to perform the computations. These are the signals and their SI units: Rotor speed - Radians/ sec
