Краткое описание

This paper considers alternative ways of correcting a control system in order to improve the precision characteristics of the automatic control without affecting the stability margin. In high-energy systems in thousand-megawatt drives it is desirable that the transition process avoids overshoot. The static precision is increased using the Smith predictor, and the dynamic precision is improved using a compensation loop. The proposed correction scheme can be applied in control systems for the airflow parameters, such as the Mach number in the wind tunnels at TsAGI. This allows one to improve the research quality and reduce the time required for testing in wind tunnels T−106, T−109, and T−128.
