MathWorks is please to offer a new training course, Power Electronics Control Design with Simulink and Simscape.

This one-day course focuses on modeling and controlling power electronic systems in the Simulink® environment using Simscape Electrical™. Topics include:

• Modeling direct current (dc) power electronic components
• Controlling the level of fidelity in a model
• Developing controls for power electronics
• Modeling three-phase alternating current (ac) power electronic components
• Controlling power electronics for motor drive applications

Hi, Currently modelling an reciprocating engine coupled to a linear PMSM motor/generator for my PhD. I have downloaded the "Model File Package for Motor Control Design Public Video" simulink model.

Is it possible to convert to rotational PMSM simscape plant model used for a linear PMSM model? As there are none in the library to just drag into the existing control model.

Any ideas i can represent a linear motor based on this existing control model?

My output from the machine needs to be linear position w.r.t, with a total stroke of approximately 100 mm. Can i convert the rotational constant speed input at port "W" to a sinusoidal velocity profile (such that it replicates the velocity profile of a linear machine)?

Any help would be great.

Thanks

Hi everyone,

I am trying to control an actuator with brushless DC Motor in Simulink. At one point, I am in need of the motor rotation and the only parameter available to me is the duty cycle and the direction of rotor. I knew that it is not possible to calculate rotation from duty cycle. In case if some one have idea about this or some suggestions, could you please share with me

Thanks in advance

Visit MathWorks at booth 218 during the IEEE Energy Conversion Congress and Exposition (ECCE) in Baltimore, Sept. 29 - Oct. 3. We will be partnering with Speedgoat to show real-time simulation solutions for power electronics control design. Also, join us for a panel session, The Role of Simulation Software for Power Electronics Control Design in Education, that will be held Thursday, Oct. 3.

Many microcontroller companies support motor control development using Simulink and Embedded Coder. Here are some interesting reads about some of them. Do you know others? Let us know with your reply.

With the need for higher sampling frequencies, power electronics control engineers are moving some of their controller implementations to FPGAs or FPGA-based SoCs. Besides the use of wide-band gap semiconductors (GaN and SiC), what other reasons are driving the need for higher controller sampling frequencies? Let us know your thoughts.

If you have not seen this yet, in Release 2018b we added several examples to Simulink Control Design that show how to use this product to tune the gains of field-oriented controllers.

The first two examples make use of Closed-Loop PID Autotuner block . We show how to use this block to tune multiple loops in the motor control system, one loop at a time.

One of the examples shows tuning the controller gains for a PMSM:

Tune Field-Oriented Controllers Using Closed-Loop PID Autotuner Block

The other example shows how to tune four loops for an asynchronous machine (inductance motor):

Tune Field-Oriented Controllers for an Asynchronous Machine Using Closed-Loop PID Autotuner Block

This approach works well when you have initial gains that provide stable response, and you want to fine tune the controller to improve performance.

What do you do when you start with a new design and need to design your controller from scratch? That is what the third example is showing. Here we design all 3 loops (id, iq, speed) for a PMSM by running an AC sweep to compute a frequency response, then identifying a state-space model using System Identification Toolbox, and finally tuning all 3 loops simultaneously to provide desired performance.
