hii, i am doing my main project in university on "speed control of a car". i am using PID controller for regulating speed. i have SET SPEED (which is known) and ACTUAL SPEED (which is obtained from the speed sensor). i tried to write program but didnt succeed. can anyone help in this regard

So... When did the OpenCores "cores" forum turn into a "help me with my homework" forum?
Come on guys... Do your own work... ---

Hi Zhu Xu,
I just utilize your shared PID core in my project, so i want to check something with you here As for the coefficients setting, i have some doubts/questions as following: �16-bitsignedcoefficientanddatainput:Kp,Ki,Kd,SP and PV. -Q1: these coefficients should be unsigned rather than signed, right? -Q2: Kp,Ki,Kd are all fractional inputs, right? or some bits stands integer part? what are their valid value region? �32-bitsignedu(n)output. -Q: is it a 32-bit integer signed output? should have infractional part, so i just want to know how wide the infrational part is, 16-bit? thanks a lot Mengjie |
