Mechatronics Engineering, Computing and Information Technology. Application Research of Stepper Motor Control with Normally, the back-emf signal has coupling noise from the PWM signal which is used to vary the speed of the motor. I do understand the technical issues and it comes down to a practical implementation that is possible, within budget and reliable. What speed do you want these to go at in terms of steps per second.

Application Research of Stepper Motor Control with TMS320F2812

Xu, Bin Li, Q. Are you trying to do this?

Not that precisely but something similar. As the development of the Microprocessor technology, Power electronic technology, Motor manufacturing technology and modern control theory, Variable frequency system is used more and more widely.

Application Research of Stepper Motor Control with TMSF

So it looks like it is possible and desirable to have a single Ardunio control all motors, not entirely convinced how to achieve this. I have some steppers on order ATM should get them soon. The motors will be doing separate things that the central controller will need to coordinate. What I want to be able to say to the stepper is “go to 43degrees”, “go to 23degrees” So steepper I really need is a controller on the stepper that doesn’t need me to to send PWM instructions but rather can be told what position steppet rotor needs to be in.


Just do not think of using more than one Arduino it will cause you more trouble than it is worth. To get really good answers start at the beginning! This paper introduces how to realize the stepper motor control based on digital signal processor TMSF I think I’m missing something. How can I control 40 steppers at the same time? Absolutely with the experimentation.

The results indicated that the performance of SRM speed control system by fuzzy PI control algorithm is obviously better than that by conventional PI control algorithm. Assuming you use stepper drivers that take step and direction signals each motor will require two Arduino pins.

For 40 motors that will probably mean two Megas. No you can use one Arduino to control as many stepping motors as you like.

I was thinking of using an I2C address for each Arduino, cycling through them and directing where they should be. At ten seconds per rotation you have the time.

I would be more than happy for someone to point me in the direction of how this can be achieved. Servo’s will need modification as I need to do continual rotation. The stability of steppet is analyzed. Timing is not an issue everything is relatively slow one full rotation will never be faster than 10 seconds. I need to be able to centrally control all the steppers from a single control.


Use port expanders to get the extra pins. So it is difficult to detect the zero-crossing point accurately when the motor work at low speed. And the experiments verified the good control stwpper and dynamic characteristics of the system. Everything runs on smoke, let the smoke out, it stops running I figure steppers with hall-effect devices for a zero reference. Thanks for all your help. Cost is not an issue. They work together to achieve and improve the performance of the control system.

The control system is implemented from both hardware and software parts.

This could mean the need for more Arduinos. Each of the drive units will have to be time synced so that you do not notice the delay between addressing the first to last unit.
