Simulink Simulator for a Brushless DC Motor

Complete simulator for brushless dc motor based on MATLAB R13.

Description

This is a comprehensive simulator written to simulate a trapeziodal back emf, star wound brushless dc motor. Complete flexibility in varying various model parameters have been provided. This is the result of the undergraduate project taken at National Institute of Technology Karnataka (INDIA) with a team of Mr Jora Gonda, Raghunandan SN and Manas Bhat.

About 25 different simulation variable can bve monitored. This is intended to be a freeware so that with time the product can improve.
The approach used has been to avoid the use of Simpower (power electronics) block set which demand huge processing power and memory. The core BLDC module 'mybldc' is logical and the inverter has been made out of logical elements resulting in a faster simulation.

• Required Products: EDA Simulator Link IN; EDA Simulator Link MQ; Embedded IDE Link CC; Embedded IDE Link TS; Gauges Blockset; Global Optimization Toolbox; Image Acquisition Toolbox; Image Processing Toolbox; Instrument Control Toolbox; Mapping Toolbox; MATLAB Builder EX; MATLAB Builder JA; MATLAB Builder NE; MATLAB Compiler
• MATLAB release: MATLAB 6.5 (R13)
• Other requirements: 1.RAM: 256 MB or more (although 128 MB would do but it would be slow) 2.A good graphics card

Hello,
i m working on this project so expecting more information about it

[raj kapor]

Hi,

I'm involved with a project to design a BLDC motor control with DSP controller.
I found that your simulink simulator for a BRUSHLESS DC MOTOR ( Complete simulator for brushless dc motor based on MATLAB R13) in Matlab central - File exchange site very interesting and useful.
I've tried to simulate your simulation model in my Matlab version 6.5, but I'm getting some error.
Below are the 3 errors I'm getting from your simulink simulator model.
1) Error in S-function block 'mybldc_mdl2/ESTIMATE/S-Function': S-Function 'calc_core' does not exist.
2) Error in S-function block 'mybldc_mdl2/mybldc/S-Function': S-Function 'MYBLDC2' does not exist.
3) Error in S-function block 'mybldc_mdl2/zero-cross/M-file S-Function': S-Function 'delay' does not exist.

I'm realy interested to find out and troubleshoot these errors, I realy hope that you can help me in this.
You can reply my mail if you have any idea how to troubleshoot these errors.

[santosh ugale]

hallo;we are working on a project "speed control of dc motor using automatic controller(PI action)with MATLAB simulation.we have just downloaded your zip file .we are working in matlab 6.5 .it is very interesting.we found some blockset of PI controller but there is trouble in finding its parameters (gain,input).please send us relevant info for simulation. "thank you".

[raghuram mudududla]

this is the best simulation i have ever seen ..........Ila

[yuyang wang]

I have downloaded this file but cannot unzip it.There seems to be some errors of the zip file. Can you be kind enough to send me the file?Thank you.

[derust ssert]

hallo;we are working on a project "position control of dc motor using automatic controller(PID action)with MATLAB simulation.we have just downloaded your zip file .we are working in matlab 6.5 .it is very interesting.we found some blockset of PID controller but there is trouble in finding its parameters (gain,input).please send us relevant info for simulation. "thank you".

[sri chowdary]

good but need some improvement

[chitra laksmanan]

respected sir,
iam doing p[roject in this simulation area.i downloaded and simulated the bldc model.but its showing some error in the S function.how to rectify that one?please guide me.

[bouhrik moussa]

hello, goog working, send me modeling of dc motor brushless simple model,please

good work

[bhavesh BHUT]

ineed it for my project

[adi sahu]

 

[sivakumar R.J]

Excellent one.. iam having one doubt. can u give me the rating of your motor..because iam having the transfer function values of my BLDC motor but not the rating..can u please tell me how we have to find the rating of the motor from the J,L,R,B,K values and vice versa... please its important for our project

[simbu arasan]

i want the dc motor simulation for my project.please send it to my mail.

[zhang jiabao]

it's a good thing.

[Seyyed Hamzeh Hashemi]

[kaliamoorthy Mylsamy]

Yes it is really intresting to understand how to model BLDC using Matlab.

[Lekshmi Balan]

i want dc motor simulation for my project. Please send to my e mail id

[M. Murali Rama Krishnan]

Dear Sir,
 I already mail you regarding... your Brushless DC motor... With out Documentation it's uneasy to understand sir... Please Send me a copy of Documentation for this Brushless DC motor... which will help me out from this problems...
    I have mail you twice to
             [e-mail]
  But I haven't got any reply form you...
  Please help me... Sir...
 After Understanding the complete projects then only I may Apply Some special techique using the BLDC Simulator...

  My E-mail id:
               [e-mail]
 I hope... you will positive in your reply...
  
Regarding Project Comment:
         I cannot comment because I am beginner in Matlab as well as Simulink... But I cannot put Excellent to this project because I am not at all understood the complete project....

     It's Just all Matlab Files... which help me to run... I may not understand... why the IC, Controller MOD, State Diagrams were installed in this Brushless DC Motor... etc...etc... By the way I have lot questions regrading Brushless DC Motor Using the State Space Modelling.... Please Send me the ocumentation for this project...

     I hope the GOD wishes you
            where ever you go...

[ali moh]

thanks

[salah Mohamed]

The current shape is compeletly wrong sir. It should be a square wave with zero duration between each positive and negative pulse!!!! but the current in this simulation is totally distorted and does not follow the litereture. why is that?

[Lokesh Amarnath]

 

[rambabu surala]

hello sir i am doing project bldc motor with fuzzy controller with your same lin model but i am getting errors. please teel to how i have to apply fuzzy to simlink model

[vu hoang anh]

give me way how to operate it

[yirga alemu]

it is good go ahwead

[MEHRAJ MATTA]

 

[jiashun lai]

It's very good,I have look for it fro a long time!Thanks a lot!

[dwarakanadh sai]

i think it is very useful for the students,,,,
i have to congrat the author to do these type of things.....

i am requesting to all authors that...
create model for OP-AMP....
and put like this..........

[chaitanya Bommisetty]

I have simulated the model after reseting using the default values that were already set in the model. The problem is that in the open loop operation of motor i.e before the threshold time, there is a problem in the state machine of CONTROLLER_MOD. Since at start up the reference and actual currents are zero the state machine was not able to decide state and giving parse errors.

I really need brushless dc motor based on MATLAB model.

[Bvhari Vashvtri]

Hi, good job with the MATLAB simulink stuff. I can't get it to run in 2007b... any ideas of how to get the simulations to run? The m-files don't work either.

Hello,

I’m working on a similar project and I think your work is OK.
But your explanatory document contains some unclear stuff (e.g. you use the notation B for both flux density of the field and friction coefficient, you don’t explain BM, RI, DF in the document, and so on…).
What would have been very useful for me:
- to have a list with all the motor parameters and their specific values (the default used values)
- in the Simulink blocks I would have added the units for each parameter
- it’s still not very clear for me the way in which you have calculated the A matrix dealing with the fact that you use LA, LB and LC which are relative.

Anyhow, thank you, it was good input for me.

hi pls help me... pls send MODELING OF BLDC motor

[s sakthi]

modeling and simulation of BLDC motor..send the details plz...

[china jiliang university]

there is something wrong with the model，when i run the model,it turns up the summary:"At time 0.0005159318861234992, simulation hits (1000) consecutive zero crossings. Consecutive zero crossings will slow down the simulation or cause the simulation to hang. To continue the simulation, you may 1) Try using Adaptive zero-crossing detection algorithm or 2) Disable the zero crossing of the blocks shown in the following table." I don't know why,could you tell me the reason.thanks! My matlab version is R2010a.
