         Hi friends, i am using a solid state relay for controlling the speed of an induction AC motor(1/4HP) by applying PID algorithm in LPC2129 Microcontroller & i know about the Triac firing angle(Phase angle control)using the zero crossing interrupts. 

    i need a source code for LPC2129 microcontroller or 8051. Any ideas please answer.  

     

     

     

     

     

    Regards,

    Vignesh DS

    Hi,

     

    I am working on ARM7.

     

    Do you know how to implement PID Controller ? I know remaining part..

    to use PID you need feedback of current motor speed

    how you are getting it?

    how you are setting motor speed?

    because the PID works on error and

    error = set speed – current speed

    Thaks for replying my post.  I am using WSH130NL a unipolar based Hall effect sensor to read the instantaneous speed of the AC motor. I know some ideas to implement the PID concept in LPC2129 Microcontroller. But the TRIAC Firing concept is littlebit difficult to me in LPC2129 Microcontroller.

    Hi,

     

    We can fire TRIAC from the PWM Pulses generatd from ARM7 controller…

     

    For safety, we must add optocouplerin between…!!!

     

    LPC21XX has inbuilt PWM generator..!!

     

    With that we can generate pulse of required duty cycle…
