Abstract

The magnitude optimum (MO) technique provides a non-oscillatory closed-loop response for a large class of process models. The idea of the method is to find a controller that makes the frequency response from set-point to plant output as close as possible to unity for low frequencies. Recently, the basic frequency domain method, has been improved, using multiple integration of the process time response for calculating the parameters of the PID controller. In the present paper the method is extended to PID controllers with filtered derivative term.
