HELP PID controller ...Urgent !!!!!

hello everybody  

actually i'm working on my final year project that deals with process control which requires the implementation of a PID controller  

and i'm wondering if this can be done using VHDL ? if yes please does anyone have a sample code ? Or if there exist an IP Core for PID controller that can be instantiated using SOPC ??? 

 

 

PS: i use nios ii softprocessor and cyclone II fpga of the DE2 board  

i really know a little concerning PID controllers  

 

please i really need any help .....it's urgent 

 

thank u very much in advance

Software language will be much easier to implement PID controller then using HDL (vhdl or verilog).So you should go for " C " language to program PID controller. 

You will find so many readymade codes but important thing is "tuning" and understanding of each parameter effect (i.e P ,I,D) like if "I" parameter is more,then more oscillations will be occurred.So reduce it and increase "P" like that. 

I have just recenly done to control my Dc motor.
