Abstract. A new method of robust controllers design for linear system with delay is developed. The system is supposed to be rude with respect to parametric uncertainty and variation of the delay value; the controllers implement traditional and associated with them control laws. The proposed approach is based on the aperiodic stability criterion and the dynamic compensation method. The transfer function of the controller is determined analytically with the use of the transfer function of the object under the control.

Keywords: linear systems, robust control, regulating laws, the criterion aperiodic stability, dynamic compensation method
