Abstract: This paper deals with the design of PI controllers which achieve the desired frequency and time domain specifications simultaneously. A systematic method, which is effective and simple to apply, is proposed. The required values of the frequency domain performance measures namely the gain and phase margins and the time domain performance measures such as [...]
At one time, I worked in a large continuous process plant that had alarms coming in constantly. The operators could hit the “Silence” button in their sleep.
