The Smith scheme of including a consecutive compensator in the direct branch of a designed system is considered. The scheme is used as an effective way of solving the problem of removing the link of pure delay beyond the closed loop of the system to ensure its stability regardless to the delay magnitude. The system property is based on additive signal compensation, which is not a robust procedure. A correct implementation of the procedure requires an accurate knowledge of the delay value and ordinary parameters of the polynomial part of the plant transfer function. Sensitivity of processes in the projected system to the deviation of ordinary parameters from their nominal values is analyzed.
