Hello,
The MC9S08QD2 device does not have sufficient resources of flash and RAM to support floating point calculations. You would need to use a much larger capacity device for this purpose. Even so, the control process will be slow for an 8-bit device, and will limit the ADC sampling rate.
Depending on your sampling rate requirement, you might need to use a 16-bit MCU, or even a 32-bit Coldfire device for this application.

hello ...
i can understand , but i'm using PID for only output current for boost converter.
can you help me...what is the procedure for implementing PID control...if you have any paper or information on PID ...jus send the link, so that i will check once.
for implementing PID , which microcontroller is best...
suggest me, which microcontroller is to be used and provide me some information on , how to implement PID in microcontroller.
thanking you
