Controller tuning procedures that identify the process using an ultimate period method assume that the process can be sufficiently modeled in the frequency range important to control with two parameters. Ziegler-Nichols' and Shinskey's tuning methods are examples of these procedures. This paper discusses an extension of these methods, using two frequencies… CONTINUE READING
