The invention discloses a controller oscillation divergence control method, a controller and a storage medium. The controller oscillation divergence control method includes: collecting the first controlled variable value in real time within a preset adjustment period, and according to the The first controlled variable value and the preset stable value are calculated to obtain the positive deviation value and the negative deviation value; judge whether the positive deviation value and the negative deviation value meet the preset rules; if the positive deviation value and the negative deviation value meet the According to the preset rule, it is confirmed that the oscillation phenomenon occurs; the command mean value is calculated according to the control command parameters sent to the external device, and the command error is calculated according to the command mean value and the preset command value; and the absolute value of the command error is judged Whether it is smaller than the preset dead zone width; if the absolute value of the command error is smaller than the preset dead zone width, enter manual mode operation. The invention can realize manual adjustment when the oscillation divergence phenomenon of the controller cannot be automatically adjusted.
Description
technical field [0001] The invention relates to the technical field of automatic control of thermal power plants, in particular to a controller oscillation divergence control method, a controller and a storage medium. Background technique [0002] At present, the national power industry is developing faster and faster, and the level of automation is getting higher and higher. DCS control has been widely used in various thermal power plants. The automatic control system in DCS generally adopts the conventional PID control strategy. In general, the control system can achieve a better adjustment effect through automatic adjustment of the setting parameters. However, if the parameter setting is strong, or when a large disturbance occurs, the phenomenon of oscillation divergence cannot be automatically adjusted by setting the parameters. [0003] Therefore, it is necessary to provide a controller oscillation divergence control method to solve the above technical problems. [00...
