View Full Version : Common controls-related circuits / components / algorithms / resources

11-25-2010, 02:53 AM

I have been getting into the Propeller recently and really liking it. I have a Master's Degree in Mechanical Engineering with a concentration in controls, but don't know much about implementation using electronics. I am interested in implementing the theory I have learned into actual controls projects. Think along the lines of Segway type projects, autonomous flight, or projects of similar scale and complexity.

One thing that I am curious about is if there are some common "go to" circuits, components, or algorithms that are frequently used for some of the more complex controls projects. I don't mean "control" as in, "the microcontroller is controlling that servo." I mean "control" as it relates to control theory (PID, MRAC, and so on). Often control theory dictates use of matrix manipulation and DSP processing. I know the theory but I am not sure about the best way to accomplish things in the electronics world that are quite easy to do with a pencil and paper.

Please share:
-Common components that are used (DSPs, etc.)
-Good online resources for this topic
-Good books on this topic
-Anything else that comes to mind

Thank you!

Look through the Propeller Object Exchange for objects that implement common algorithms, like PID.

Look at the book "Programming and Customizing the Multicore Propeller Microcontroller", particularly Chapter 6 on the DanceBot balancing robot.

That book looks really cool. Thanks for the tip, Mike. And it's available on Kindle!

Are there any popular chips or circuits out there?

If you are looking for chips and circuits used with the propeller for control applications take a look at the OBEX. There are drivers posted there for a variety of ADC's, sensor IC's, motor control IC's, and other driver IC's. Then you can download data sheets and application notes from the chip suppliers.

I would visit gadget gangster. Nick has some kits that feature "popular" items. The designer kit comes with a set of components he's picked for people building new things, and it is a nice starter selection.
