Abstract
A PID autotuning algorithm based on relay feedback has the capability of exploring different points of the process frequency response before performing the actual tuning procedure. In addition, the algorithm minimises the amount of a prioriinformation required on the process; in fact, the user is only asked to specify the minimum phase margin required for the closed-loop system. Some experimental results, obtained by laboratory simulation, are also presented.Keywords
