PID controller of a dc motor using a microcontroller

I've got lab assignment of the above topic, i hav got little knowledge of the things involved. Can someone please guide me through, so i know where to start from. Thanks

Google it man !!!

One important advice when you are using a microcontroller/fpga to control a dc motor is DO NOT CONNECT THE MOTOR DIRECTLY TO THE MICROCONTROLLER/FPGA. You need to generate PWM signals using the microcontroller. Higher the duty cycle of the PWM signal, the faster the motor turns.

Use some kind of buffer/isolation. If you have to control the direction of the dc motor also, then you need to use a H-bridge L298.

When you are using feedback(PID controller) to control the position of a dc motor. You need to figure out whether just proportional controller is enough to control the position of dc motor or not. Rather than using all the proportional/integrator/derivative control parameters. In order to determine these constants, you need to do a lot of trials.

Hope this helped.

By searching the Google and the forum would be the best option

You may try these examples **broken link removed** and try-out using microcontrollers

You might want to use LM628 / LM629 to make it easier to implement PID.

Thanks for your reply. What i am doing is controlling the speed of the dc motor using a microcontroller and using a PID controller for stability of the system and to eliminate error. My problem is, i have never used or built a pid controller before. I understand the uC will generate the pwm signal but i dont understand where the PID will fit in and also where the uC will fit in as well. i would be glad if u can help me with that.Thanks
