This is a response to a request for info on PID controllers. I recommend getting ahold of a book called "Programming Microprocessor Interfaces for Control and Instrumentation". The author is Michael Andrews and it is published by Prentice-Hall, INC. The chapter on "Process Control Digital Algorithms" describes the PID(Proportional Integral Deferential) controller, along with several others. Code for the PID is provided in the book in 6809 assembler. I think the book is available through Computer Literacy in Sunnyvale,CA. I might of gotten it at Stanford Technical Book Store, tho. The real heavyweight in the field of servo control is Benjamin Kuo. He has written several excellent texts on control theory. See for example "Analysis and Synthesis of Sampled-Data Control Systems",Prentice-Hall 1963. Mike
