Synthesis of Robust PID Controller by the Maximum Stability Degree Criterion

The new approach for determining and imposing the maximum stability degree of the system in function of the control object parameters and the number of tuning parameters of PID controller is proposed in this work. The elaborated method of synthesizing the typical controllers represents a simple analytical procedure, that requires the reduced volume of calculation and not impose the restrictions on the complexity of control object. The control systems synthesized by this criterion can be characterized by the high speed, a low overshot and good robustness.
