Abstrakt: A new method for calculating the tunings of PID controllers for linear plants with a time delay minimizing the quadratic criterion I is considered. The idea of the proposed method consists in obtaining the complex frequency response of the optimal linear controller followed by approaching to it the complex frequency response of a PID controller in the essential frequency band using the least squares method.
