Properly tuned controllers should ensure correct and unobstructed functioning of the system, i.e. process. Using ideal relay as nonlinearity in process of auto-tuning gives significant errors in estimates of the ultimate gain and ultimate period. In this paper mentioned lack is overcomed by introduction saturation relay, where control system of condensate level in condenser of turbine in thermal power plant Gacko is used as a model. Due to the constant striving to reduce energy consumption, above settings are implemented in the system for which is proposed strategy which provides energy savings, i.e. includes frequency regulators.
