Mechatronics with MATLAB and Simulink, Part 1: Accuracy, Speed, and Power Consumption

[@KAFA2020]

Oh beautiful. very good explanation. May you live a long life Full of gladness and health . May all God's blessings descend upon you. May peace be within you may your heart be strong. May you find what you're seeking wherever you roam.?

I would like to learn such modelling from basics. Any links?

[@terrydenery7078]

I am curious if you have continued to watch this series. We have 5 videos posted now, and two more will be posted in the next couple of weeks. If possible, please let me know if the series is moving in a direction where it fills you in better on the basics. . . . . I also recommend the videos produced by Steve Miller on Simscape and Physical Modeling. Steve has a very good presentation style, and he focuses in detail on the basics of building mechanical, electric, and hydraulic models with Simscape and Simulink.

Thanks Terry. I had just found part 1. I followed other parts too. This series is what I wanted to learn. Thanks :D

[@terrydenery7078]

Thanks.

Interesting project. Will be amazing to see full explanation in details!

[@terrydenery7078]

We now have 5 videos posted for this series, and will be posting 2 more in the next two weeks. I am curious if you have continued to watch the series, and if you think that it is providing useful explanations on how to use these tools and benefit fully from them. Thanks.

Do mechanicals engineers write programs in c++? Can a mechanical engineering degree get you as a programmer without having a Computer Programming degree?

[@harisbagwan3427]

Βαλάντης Στυλιανού In most universities very little programming exposure is available to Mechanism Engineers. But nonetheless one can learn the C++ language or any other and master it through practice. But hardly, does one pursuing a Mechanical degree write a line of code for most semesters.

Hello Terry, I have problem when export file to simscape multibody. I haven't this choice ?

[@karthicksridhar6719]

which software are you using?

[@KAFA2020]

Could I use cinema 4d for such simulation?

[@asifnizamani7513]

sir i have labview which get from university sir i don't matlab because my university have not matlab is it your simulink work in labview.

[@SyncXwave]

where are you know currently.

Terry, Thanks for the awesome videos :) I have a very basic problem in the simulations I'm doing in Simulink multibody. I have a simple pendulum and I can calculate the torques(using the revolute joint) from the desired angular motion. Now I'm trying to get the same torques to produce the original motion (torques provided to the revolute joint and motion automatically computed). When I don't have any gravity acting on it the torque values are able to produce the same motion (more or less, some error is expected). But when I have gravity turned on, the torque values calculated by providing motion as input (with gravity on) make the model go crazy(it just starts spinning around!). What do you think I'm missing? Everything else in the models remain the change and I'm just switching the actuation of the revolute joint. Thanks!

Hi Gaurav, Video 7 of this series is focused completely on answering this question. Basically you are attempting to apply feedforward control with no feedback. Feedforward control is a beautiful thing, but you will always need a little feedback to reject the error. Please take a look at Video 7 on Feedforward Control, and let me know what you think. Thanks. -Terry

Thanks Terry. I went through the whole series and found the answer to this question. Thanks for making these tutorials!

[@terrydenery7078]

Thanks for watching the videos!

[@amr.a-m8350]

Good tutorial where there are optimizations?

[@rubocadete]

Nice!

Nice video Terry
